Oneness and existence of the solution to the problem of boundary values for a set of second-order partial differential equations
الخلاصة
Abstract: Most of the problems of mathematical physics, when solving them, result in solving one or more partial differential equations with imposed initial and boundary conditions. This is known as boundary value problems for differential equations. This paper studies the solution of a set of parabolic and hyperbolic partial differential equations with boundary conditions imposed in different regions of the y o x plane
