Qısa məlumat

In this paper, we investigate a minimal operator corresponding for the second order differential operator expression with an exit from the space, study its self-adjoint extensions, also for one particular self-adjoint extension, corresponding to boundary value problem with some rational function of eigenparameter in boundary condition, establish asymptotics of the spectrum and derive a trace formula.
