Physically, eigenvalues correspond to bound states in quantum me-chanics or harmonic oscillations near imperfections such as cracks and holes in elasticity theory. They play an important role in applications in science and industry such as non-destructive testing theory of sensitive structures (e.g. wings of air planes, nuclear components etc.).\r\nMore specifically we consider the asymptotic behaviour of the discrete eigenvalues for small perturbations which arise from a change of the boundary conditions on a small sub-set of the boundary. From the spectral-theoretic point of view this kind of perturbation is of particular interest since standard methods such as the Birman-Schwinger principle for handling additive perturbations of operators fail. To determine the asymptotic be-haviour of the discrete eigenvalues we shall use a pseudo-differential approach which is based on an analysis of the corresponding Dirichlet-to-Neumann operator. This method is of benefit mainly because it uses the symbol expansion of the Dirichlet-to-Neumann operator in local charts and the behaviour of the resolvent near the spectral minimum. ... \"", "language" : "English", "bibtexKey": "hanel2015singular" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2fec3fac8cf1e585cfd5f4332f14e4e53/elkepeter", "tags" : [ "iadm","Hänel","elastic","Weidl" ], "intraHash" : "fec3fac8cf1e585cfd5f4332f14e4e53", "interHash" : "fa7519e99a0f653c8cd0e56266aa713f", "label" : "Eigenvalue asymptotics for an elastic strip and an elastic plate with a crack.", "user" : "elkepeter", "description" : "", "date" : "2021-10-08 11:33:49", "changeDate" : "2021-10-13 11:54:00", "count" : 2, "pub-type": "article", "journal": "Quarterly journal of mechanics and applied mathematics","publisher":"Oxford Univ.
