Abstract

We consider self-adjoint realizations of a second-order elliptic differential expression on R n with singular interactions of δ and δ'-type supported on a compact closed smooth hypersurface in R n. In our main results we prove spectral asymptotics formulae with refined remainder estimates for the singular values of the resolvent difference between the standard self-adjoint realizations and the operators with a δ and δ'-interaction, respectively. Our technique makes use of general pseudodifferential methods, classical results on spectral asymptotics of ψdo's on closed manifolds and Krein-type resolvent formulae.
