Most of mathematical physics problems can be translated into solve one
partial differential equation or more with specific initial conditions and
boundary conditions. This is called the boundary value problem for the
differential equations.
This
paper studies the solution of systems of hyperbolic and parabolic
partial differential equations assuming some boundary conditions in different
domains in the plane xoy.
In this paper we have proved theorem about the existence and uniqueness of
the solutions. This article is considered to be a continuation to the works of
Alimove, Ssallah Aldinov, Gooraev and Alhamad.......
