Periodical problem is of common occurrence in many applied fields. In this paper the equation with periodical condition and small parameter is considered. The problem will lead to large oscillation since the parameter is small. The boundary layer function is presented firstly. The smooth component is constructed by the boundary layer function secondly. The error estimation of analytical solution is...
In this paper the equation with periodical condition and small parameter is considered. The equation will lose boundary condition and lead to large oscillation in boundary layer. The properties of the equation is studied firstly. The analytical solution is decomposed into the smooth component and the singular component. The asymptotic solution is proposed secondly. The asymptotic solution is used...
