The theorem of Floquet on the representation of the fundamental matrix [<span class="zbmathjax-textit">G. Floquet</span>, Ann. Sci. Éc. Norm.

Lyapunov</span> [The general problem of the stability of motion, London (1992; <a href="/0786.70001">Zbl&nbsp;0786.70001</a>) (Originally: Kharkow, 1892) (Russian)], and, finally, the theorem on the stability of periodic solutions are generalized for DAEs. The authors show that the results for DAEs are as clear and simple as for regular ordinary differential equations (ODEs). <br class="zbmathjax-paragraph">In contrast to regular ODEs, DAEs have only implicitly given dynamic parts. To work out and utilize this implicit structure, a decoupling technique is applied, which goes back to <span class="zbmathjax-textit">E. Griepentrog</span> and <span class="zbmathjax-textit">R. März</span> [Differential-algebraic equations and their numerical treatment, Teubner-Texte Math. 88, Leipzig: BSB B. G. Teubner (1986; <a href="/0629.65080">Zbl&nbsp;0629.65080</a>)]. Via a proper decoupling, the classical procedures of ODE theory [see for example <span class="zbmathjax-textit">L. S. Pontrjagin</span>, Gewöhnliche Differentialgleichungen, Mathematik für Naturwissenschaft und Technik. 11. Berlin: VEB Deutscher Verlag der Wissenschaften (1965; <a href="/0134.30201">Zbl&nbsp;0134.30201</a>)] become applicable. The authors prove, that each linear DAE with periodic coefficients is periodically equivalent to a constant coefficient DAE in Kronecker normal form. The article contains a result on the stability of the trivial solution in the case of nonautonomous DAEs with a constant linear part and a small nonlinearity.<div class="reviewer"> Reviewer:&nbsp;<a href="/authors/?q=rv%3A7951">S.Siegmund (Augsburg)</a></div> <div class="clearfix"></div></div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A1115476">Cited in <strong>17</strong> Documents</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A34A09" title="MSC2020">34A09</a> </td> <td class="space"> Implicit ordinary differential equations, differential-algebraic equations </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A34C25" title="MSC2020">34C25</a> </td> <td class="space"> Periodic solutions to ordinary differential equations </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3Adifferential+algebraic+equations">differential algebraic equations</a>; <a href="/?q=ut%3AFloquet+theory">Floquet theory</a>; <a href="/?q=ut%3Amonodromy+matrix">monodromy matrix</a>; <a href="/?q=ut%3Astability+of+periodic+solutions">stability of periodic solutions</a>; <a href="/?q=ut%3AJFM+15.0279.01">JFM 15.0279.01</a></div><div class="keywords"> <h3>Citations:</h3><a href="/0786.70001">Zbl 0786.70001</a>; <a href="/0629.65080">Zbl 0629.65080</a>; <a href="/0212.43002">Zbl 0212.43002</a>; <a href="/0134.30201">Zbl 0134.30201</a>; <a href="/15.0279.01">JFM 15.0279.01</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">&times;</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 0903.34002" data-ciurl="/ci/01115476" data-biburl="/bibtex/01115476.bib" data-amsurl="/amsrefs/01115476.bib" data-xmlurl="/xml/01115476.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/01115476.pdf" title="Zbl 0903.34002 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/10.1006/jmaa.1997.5714" aria-label="DOI for “How Floquet theory applies to index-1 differential algebraic equations”" title="10.1006/jmaa.1997.5714">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">Barz, B.; Suschke, E., Numerische Behandlung eines Algebro-Differentialgleichungssystems, RZ-Mitteilungen 7 (1994)</td> </tr><tr> <td>[2]</td> <td class="space">Hanke, M.; Griepentrog, E.; März, R., Berlin Seminar on Differential-Algebraic Equations, Seminarbericht 92-1 (1992) &middot; <a href="/1541.34002" class="nowrap">Zbl 1541.34002</a></td> </tr><tr> <td>[3]</td> <td class="space">Farkas, M., Periodic Motions (1994), Springer: Springer New York &middot; <a href="/0805.34037" class="nowrap">Zbl 0805.34037</a></td> </tr><tr> <td>[4]</td> <td class="space">Floquet, G., Sur les équations differentielles linéaires à coefficeints periodiques, Ann.
