The emphasis is on defining and visualizing concepts and relationships between them, as well as listing common confusions, alternative notations and jargon, and relevant facts and theorems. Special attention is given to detailed figures and geometric viewpoints, some of which would seem to be novel to the literature. Topics are avoided which are well covered in textbooks, such as historical motivations, proofs and derivations, and tools for practical calculations. The present paper is best read in conjunction with the similar paper on Riemannian geometry cited herein.","author":[{"@context":"https://schema.org","@type":"Person","name":"Adam

of fiber bundles and their connections is provided, in the context of gauge theories in physics. The emphasis is on defining and visualizing concepts and relationships between them, as well as listing common confusions, alternative notations and jargon, and relevant facts and theorems.

The local isotopic spaces are endowed with frames which are used as local isotopic ones. The field local of isotopic frames are considered as gauge field itself while the form of gauge connections is derived from it. The field equation for that of local frames is found. It is shown that Yang-Mills equation follows from it, but variety of solutions of the new equation is highly reduced such that no ambiguities (Yang-Wu and vacuum ones) arise. It is shown that Lagrangian for the field gives non-zero trace for the stress-energy tensor and zero value for the field of plane wave. New solutions for the fields of punctual source and spherical wave are found.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;THEORY OF NATURAL BUNDLES AND GAUGE FIELDS&quot;,&quot;attachmentId&quot;:62262102,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;work_url&quot;:&quot;https://www.academia.edu/42127207/THEORY_OF_NATURAL_BUNDLES_AND_GAUGE_FIELDS&quot;,&quot;alternativeTracking&quot;:true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/42127207/THEORY_OF_NATURAL_BUNDLES_AND_GAUGE_FIELDS"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="1" data-entity-id="9269102" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/9269102/Fiber_Bundles_Yang_Mills_Theory_and_General_Relativity">Fiber Bundles, Yang-Mills Theory, and General Relativity</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="48108" href="https://uci.academia.edu/JamesOwenWeatherall">James Owen Weatherall</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Synthese</p><p class="ds-related-work--abstract ds2-5-body-sm">I articulate and discuss a geometrical interpretation of Yang-Mills theory.

A main point is that two different concepts, number and number value are combined in the usual representations of number structures. This is valid as long as just one structure of each number type is being considered. It is not valid when different structures of each number type are being considered. Elements of base sets of number structures, considered by themselves, have no meaning. They acquire meaning or value as elements of a number structure. Fiber bundles over a space or space time manifold, M, are described. The fiber consists of a collection of many real or complex number structures and vector space structures. The structures are parameterized by a real or complex scaling factor, s. A vector space at a fiber level, s, has, as scalars, real or complex number structures at the same level. Connections are described that relate scalar and vector space structures at both neighbor M locations and at neighbor scaling levels. Scalar and vector structure valued fields are described and covariant derivatives of these fields are obtained. Two complex vector fields, each with one real and one imaginary field, appear, with one complex field associated with positions in M and the other with position dependent scaling factors. A derivation of the covariant derivative for scalar and vector valued fields gives the same vector fields. The derivation shows that the complex vector field associated with scaling fiber levels is the gradient of a complex scalar field. Use of these results in gauge theory shows that the imaginary part of the vector field associated with M positions acts like the electromagnetic field. The physical relevance of the other three fields, if any, is not known.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;Principal fiber bundle description of number scaling for scalars and vectors: application to gauge theory&quot;,&quot;attachmentId&quot;:40146046,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;work_url&quot;:&quot;https://www.academia.edu/18591572/Principal_fiber_bundle_description_of_number_scaling_for_scalars_and_vectors_application_to_gauge_theory&quot;,&quot;alternativeTracking&quot;:true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/18591572/Principal_fiber_bundle_description_of_number_scaling_for_scalars_and_vectors_application_to_gauge_theory"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="101652573" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/101652573/Advanced_topics_in_gauge_theory_Mathematics_and_Physics_of_Higgs_bundles">Advanced topics in gauge theory: Mathematics and Physics of Higgs bundles</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="143477408" href="https://independent.academia.edu/LauraSchaposnik">Laura Schaposnik</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Quantum Field Theory and Manifold Invariants, 2021</p><p class="ds-related-work--abstract ds2-5-body-sm">These notes have been prepared as reading material for the mini-course given by the author at the 2019 Graduate Summer School at Park City Mathematics Institute-Institute for Advanced Study.

Today, theoretical evidences, like string theory, suggest the need for a spacetime with more than five dimensions. The mathematical translation of the heuristic idea of a 4-dimensional classical spacetime equipped with extra &quot;small&quot; dimensions, is a fiber bundle structure π : M → M on a (4 + k)-dimensional manifold M , with fiber a compact manifold F of dimension k, more shortly a F -fibration. Kaluza and Klein used a fibration with fiber the standard circle S 1 , this fiber carrying the electromagnetic potential. Inclusion of other physical interaction would therefore require a F -fibration with F of the form F = S 1 × W , W being a compact manifold. However, with such a F -fibration, they is no naturally defined fiber diffeomorphic to S 1 at each point of the manifold, and therefore one looses the possibility to define simply the electromagnetic potential. We want to present in this paper a mathematical structure generalizing the fiber bundle, that enable the possible definition of multiple naturally defined fibers at each point of the manifold, on which therefore one can define objects that depend only on one of the components, S 1 or W , of the global (S 1 × W ) fiber. Although we do not pretend here to model precisely other known physical interactions, we present this geometric structure as a possible way to model or encode deviations from standard 4-dimensional General Relativity, or &quot;dark&quot; effects such as dark matter or energy ; (we refer to the authors&#39; article from which this paper is extracted, but whose purpose is different). Also this geometry was a starting point for the second author&#39;s new approach to a geometric unification of General Relativity and Quantum Physics ( see ). 1 Full details of this use of the multi-fibers structure can be found in [3] : S. Collion, M. Vaugon, A New Approach to Kaluza-Klein theory. arXiv.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;Multi-Fibers Bundles as a new model for high-dimensional Spacetimes&quot;,&quot;attachmentId&quot;:119473777,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;work_url&quot;:&quot;https://www.academia.edu/125428687/Multi_Fibers_Bundles_as_a_new_model_for_high_dimensional_Spacetimes&quot;,&quot;alternativeTracking&quot;:true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/125428687/Multi_Fibers_Bundles_as_a_new_model_for_high_dimensional_Spacetimes"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="101171572" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/101171572/Aspects_Of_Gauge_Field_Theory">Aspects Of Gauge Field Theory</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="267962040" href="https://independent.academia.edu/TarunPalla1">Tarun Palla</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Deccan Education Society&#39;s Willingdon College,Sangli, 2022</p><p class="ds-related-work--abstract ds2-5-body-sm">To describe successfully the properties and dynamics of the particle, we need field theory. The dynamics of gauge bosons are described by Gauge Field Theory, a type of quantum field theory. In this project, we work in four-dimensional Minkowski space. Gauge field theory is characterized by the presence of a vector field, we defined the Lagrangian for the gauge field (photon field) and showed that it is Lorentz invariant and gauge invariant. Any physical theory must be Lorentz invariant. We derived the equation of motion for the gauge field and derived all Maxwell&#39;s equations in terms of the electric and magnetic fields. We check the invariance of the action under global and local symmetry transformations using Noether&#39;s theorem. We derived the stress-energy tensor that gives us energy density, and the momentum of the field and determined the conserved charges associated with the gauge field. We then quantize the gauge field by treating each field as a harmonic oscillator. We derived the expression for vector field in terms of annihilation and creation operators. The gauge invariance implies that in four dimensions the photon has only two physical degrees of freedom</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;Aspects Of Gauge Field Theory&quot;,&quot;attachmentId&quot;:101785541,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;work_url&quot;:&quot;https://www.academia.edu/101171572/Aspects_Of_Gauge_Field_Theory&quot;,&quot;alternativeTracking&quot;:true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/101171572/Aspects_Of_Gauge_Field_Theory"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="9" data-entity-id="16939010" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/16939010/Fiber_bundles_and_Kaluza_Klein_theory">Fiber bundles and Kaluza-Klein theory</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="1052417" href="https://ronininstitute.academia.edu/ArkadiuszJadczyk">Arkadiusz Jadczyk</a></div><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;wsj-grid-card-download-pdf-modal&quot;,&quot;work_title&quot;:&quot;Fiber bundles and Kaluza-Klein theory&quot;,&quot;attachmentId&quot;:39267265,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;work_url&quot;:&quot;https://www.academia.edu/16939010/Fiber_bundles_and_Kaluza_Klein_theory&quot;,&quot;alternativeTracking&quot;:true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/16939010/Fiber_bundles_and_Kaluza_Klein_theory"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;continue-reading-button--sticky-ctas&quot;,&quot;attachmentId&quot;:76100720,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;workUrl&quot;:null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{&quot;location&quot;:&quot;download-pdf-button--sticky-ctas&quot;,&quot;attachmentId&quot;:76100720,&quot;attachmentType&quot;:&quot;pdf&quot;,&quot;workUrl&quot;:null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_76100720" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
