We study two bisingular Dirichlet problem with the additional boundary layer: 1) for the second order linear elliptic equation in a ring, 2) for linear ordinary differential equations of second order in a segment. We construct asymptotic solutions of the three-zone, bisingular Dirichlet by using the generalized method of boundary functions and obtain estimates for the residual functions.
Keywords: asymptotic solution, the Dirichlet problem, boundary functions, small parameter, bisingularly problem, three-zone problem, intermediate boundary layer, additional boundary layer.
