| dc.description.abstractEn | For a bounded corner domain Omega, we consider the attractive Robin Laplacian in Omega with large Robin parameter. Exploiting multiscale analysis and a recursive procedure, we have a precise description of the mechanism giving the bottom of the spectrum. It allows also the study of the bottom of the essential spectrum on the associated tangent structures given by cones. Then we obtain the asymptotic behavior of the principal eigenvalue for this singular limit in any dimension, with remainder estimates. The same method works for the Schrodinger operator in R-n with a strong attractive delta-interaction supported on partial derivative Omega. Applications to some Ehrling-type estimates and the analysis of the critical temperature of some superconductors are also provided. | |
