D. D. Aroev

Abstract

In this paper, we present and investigate a boundary value problem for a third-order parabolic-hyperbolic equation in the form of a concave hexagonal sphere with two types of exchange lines.

Keywords:

: parabolic-hyperbolic type, boundary value problem, line of type change, solution of an equation, integral equation, differential equation, concave hexagonal domain.
