We study the correctness of a problem with nonlocal conditions for untypical partial differential equations with constant coefficients in a cylindrical domain, which is a product of a segment by a torus. We establish conditions of the correctness of this problem for almost all values (with respect to Lebesgue’s measure) of its two chosen parameters.
