Abstract

The paper studies the solvability of the spectral nonlocal Ionkin-Samarsky problem for an elliptic equation of the second order. Some properties of eigenvalues are given for elliptic problems with non-local Samarsky-Ionkin conditions. The classical method of separating variables was used for the study.
