By means of the classical boundary value theory, of the theory of Fourier analysis, and of the principle of analytic continuation, we transform the equations into the Riemann-Hilbert problems with discontinuous coefficients and obtain the general solutions and conditions of solvability in class \(\{0\}\). Thus, the result in this paper generalizes the classical theory of integral equations and boundary value problems.</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A7334240">Cited in <strong>15</strong> Documents</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A45E05" title="MSC2020">45E05</a> </td> <td class="space"> Integral equations with kernels of Cauchy type </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A45E10" title="MSC2020">45E10</a> </td> <td class="space"> Integral equations of the convolution type (Abel, Picard, Toeplitz and Wiener-Hopf type) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A30E25" title="MSC2020">30E25</a> </td> <td class="space"> Boundary value problems in the complex plane </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3Asingular+integral-differential+equations">singular integral-differential equations</a>; <a href="/?q=ut%3ARiemann-Hilbert+problems">Riemann-Hilbert problems</a>; <a href="/?q=ut%3Aintegral+operators">integral operators</a>; <a href="/?q=ut%3ACauchy+kernel">Cauchy kernel</a>; <a href="/?q=ut%3Aconvolution+type">convolution type</a></div> <!-- Modal used to show zbmath metadata in different output formats--> <div class="modal fade" id="metadataModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title" id="myModalLabel">Cite</h4> </div> <div class="modal-body"> <div class="form-group"> <label for="select-output" class="control-label">Format</label> <select id="select-output" class="form-control" aria-label="Select Metadata format"></select> </div> <div class="form-group"> <label for="metadataText" class="control-label">Result</label> <textarea class="form-control" id="metadataText" rows="10" style="min-width: 100%;max-width: 100%"></textarea> </div> <div id="metadata-alert" class="alert alert-danger" role="alert" style="display: none;"> <!-- alert for connection errors etc --> </div> </div> <div class="modal-footer"> <button type="button" class="btn btn-primary" onclick="copyMetadata()">Copy to clipboard</button> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> <div class="functions clearfix"> <div class="function"> <!-- Button trigger metadata modal --> <a type="button" class="btn btn-default btn-xs pdf" data-toggle="modal" data-target="#metadataModal" data-itemtype="Zbl" data-itemname="Zbl 1458.45001" data-ciurl="/ci/07334240" data-biburl="/bibtex/07334240.bib" data-amsurl="/amsrefs/07334240.bib" data-xmlurl="/xml/07334240.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/07334240.pdf" title="Zbl 1458.45001 as PDF">Review PDF</a> </div> <div class="fulltexts"> <span class="fulltext">Full Text:</span> <a class="btn btn-default btn-xs" type="button" href="https://doi.org/10.11948/2156-907X.20180264" aria-label="DOI for “On solvability of singular integral-differential equations with convolution”" title="10.11948/2156-907X.20180264">DOI</a> </div> <div class="sfx" style="float: right;"> </div> </div> <div class="references"> <h3>References:</h3> <table><tr> <td>[1]</td> <td class="space">R.
