On selfadjoint extensions of symmetric operator with exit from space

Khalig M. Aslanov, Nigar M. Aslanova

Published 2020-04-16Version 1

We investigate minimal operator corresponding to operator differential expression with exit from space, study its selfadjoint extensions, also for one particular selfadjoint extension corresponding to boundary value problem with some rational function of eigenparameter in boundary condition establish asymptotics of spectrum and derive trace formula
