теорема Жордана – Дирихле On Analogue of Jordan – Dirichlet Theorem about the Convergence of the Expansions in Eigenfunctions of a Certain Class of Differential-Difference Operators Authors: Khalova V. A. An analogue of Jordan – Dirichlet theorem is established of convergence of the expansions in eigen functions of the operator Ly = αy′(x) − y′(1 − x) with the boundary condition U(y) = ay(0) + by(1) − (y,ϕ) = 0.
