Abstract

UDC 517.946+511.37

We investigate the solvability of a nonlocal boundary value problem for a differential equation with nonlinearity. Using the Nash–Mozer iteration scheme, we establish conditions of solvability of the problem in the Hörmander spaces of functions of several real variables that form a refined Sobolev scale.
