"Spectral theory of Schrodinger operator with $\delta$ - interactions".

Abstract.

We will discuss the properties of the corresponding Hamiltonians to be
selfadjoint  and  semibounded below.
A criterion of discretness spectrum of
semibounded  Hamiltonian  will  be presented.
Continuous spectrum and negative discrete spectrum
will be discussed too.

The talk is based on joint works with S. Albeverio and A. Kostenko.


Wed. 27 October at 4.30 pm in lecture room 128 (I floor, Santorio Building)
