Spectral analysis of the biharmonic operator subject to Neumann boundary conditions on dumbbell domains

José M. Arrieta, Francesco Ferraresso, Pier Domenico Lamberti

We consider the biharmonic operator subject to homogeneous boundary conditions of Neumann type on a planar dumbbell domain which consists of two disjoint domains connected by a thi…
