Regularized Asymptotics of the Solution of Systems of Parabolic Differential Equations

Abstract

The regularization method for singularly perturbed problems of S. A. Lomov is generalized to constructing the asymptotics of the solution of the first boundary value problem for systems of differential equations of parabolic type with a small parameter at all derivatives.It is shown that the asymptotics of the solution of the problem contains $ n $ exponential, $ 2n $ parabolic and $ 2n $ angle boundary layer functions. The exponential boundary layer function describes the boundary layer along  t = 0 , the boundary layer along  x = 0  and  x = 1  is described by parabolic boundary layer functions.
