Spectra of self-adjoint extensions and applications to solvable schrödinger operators
TL;DR: In this article, a self-contained presentation of the theory of self-adjoint extensions using the technique of boundary triples is given, and a description of the spectra of selfadjoint extension in terms of the corresponding Krein maps (Weyl functions) is given.
Journal ArticleDOI

TL;DR: In this paper, a scheme for computing the asymptotics of tr( e − tL ) as t → 0 +, where L is an elliptic operator of the form L = D 2 + x −2 A ( x ) and A( x ) is a family of operators satisfying appropriate ellipticity and smoothness conditions.
