The characteristic matrix function of a dissipative Hamiltonian operator

Mathematical Methods in the Applied Sciences, 2020
In this paper, we consider a singular dissipative even‐order Hamiltonian operator with a finite number of transmission conditions. Using coordinate‐free approach, we construct the characteristic matrix‐function of the Cayley transform of the dissipative operator.

Expansion in characteristic functions of the Schr�dinger operator with a singular potential

Mathematical Notes of the Academy of Sciences of the USSR, 1974
We study the spectral function of the operator −δ+v(x) in three-dimensional space, where v(x) is measurable and belongs to L2. We study the differentiability of this function with respect to some measure. Simultaneously, we give estimates of the characteristic functions of a continuous spectrum at infinity.
