Voß, HeinrichHeinrichVoß2006-02-172006-02-172003-03http://tubdok.tub.tuhh.de/handle/11420/146In [2] Conca et al. stated two inclusion theorems for quadratic eigenvalue problems the proof of which are not complete. In this note we demonstrate by simple examples that the assertions as they stand are false. Taking advantage of an appropriate enumeration for eigenvalues of nonlinear eigenproblems we djust the results.enhttp://rightsstatements.org/vocab/InC/1.0/quadratic eigenprobleminclusion theoremfluid structure interactionMathematikQuadratic eigenproblems of restricted rank - remarks on a paper of Conca, Duran and PlanchardWorking Paper2006-02-27urn:nbn:de:gbv:830-opus-205510.15480/882.144EigenwertproblemInklusionNonlinear eigenvalue problems, nonlinear spectral theory for PDO11420/14610.15480/882.144930768068Working Paper
