Abstract: | We consider a boundary-value problem for the Poisson equation with rapidly alternating type of boundary conditions in a domain
between two parallel hyperplanes. The solution of the problem is assumed to be 1-periodic with respect to all the coordinates
but one. We construct the asymptotic expansion for the solution in powers of a small parameter characterizing the alteration
frequency of the boundary conditon. We obtain an estimate for the remainder term. Bibliography: 16 titles.
