ON ONE BOUNDARY PROBLEM FOR A PARABOLIC-HYPERBOLIC EQUATION OF THE THIRD ORDER, WHEN CHARACTERISTICS OF THE FIRST ORDER OPERATOR PARALLEL TO THE X-AXIS

Abstract

 Per elapsed time studies on boundary value problems for equations of the third and higher orders of parabolic-hyperbolic type developed in a broad sense , and is currently expanding in directions of complication of equations and the area of their consideration, as well as generalizations of the problems of equations considered for them (for example, see [1 ] - [7] and others ).
