Spectral Properties of Nonself-Adjoint Nonlocal Boundary-Value Problems for the Operator of Differentiation of Even Order

Autor: Ya. O. Baranets’kyi, L. I. Kolyasa, P. I. Kalenyuk

Publikováno v: Ukrainian Mathematical Journal. 70:851-865

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 two-point boundary conditions.

On algebroid solutions of linear differential equations with algebroid coefficients

Autor: A. Z. Mokhon’ko, L. I. Kolyasa

Publikováno v: Differential Equations. 45:1124-1129

We establish a relationship between the growth rates of algebroid solutions and coefficients of nth-order linear differential equations.
