Spectral properties of nonself-adjoint nonlocal boundary-value problems for the operator of differentiation of even order

We study spectral properties of an essentially nonself-adjoint problem generated by nonlocal multipoint conditions for the operator of differentiation of order 2n and analyze the cases of regular and irregular Birkhoff boundary conditions. A system of root functions of the problem and elements of bi...
