Spectral isoperimetric inequalities for singular interactions on open arcs

of the two-dimensional Schrodinger operator with an attractive -interaction supported on an open arc with two free endpoints. Under a constraint of fixed length of the arc, we for the lowest eigenvalue of the Robi...

Strong Coupling Asymptotics for a Singular Schrodinger Operator with an Interaction Supported by an Open Arc

We consider a singular Schrödinger operator in L 2(?2) written formally as-?-??(x-?) where ? is a C 4 smooth open arc in ?2 of length L with regular ends. It is shown that the jth negative eigenvalue of this operator behaves in the ...

An Eigenvalue Inequality for Schrodinger Operators with delta- and delta '-interactions Supported on Hypersurfaces

We consider self-adjoint Schrodinger operators in L-2(R-d) with a delta-interaction of strength alpha and a delta'-interaction of strength beta, respectively that this eigenvalue inequality is strict whenever beta ...

Spectral Asymptotics for a δ' Interaction Supported by an Infinite Curve

In this paper we consider a generalized operator describing an attractive delta' interaction in a strong coupling limit. Delta' interaction is characterized by a coupling parameter and it is supported by a C4-smoot...
