Abstract
We consider mixed boundary value problem for strongly elliptic differential-difference equation and nonlocal mixed problem for elliptic differential equation in a bounded domain. We establish the connection between these problems, prove theorems on the unique solvability and on the smoothness of generalized solutions of these problems.
