摘　　要：This paper investigates the boundary value problems for a class of singularly perturbed nonlinear elliptic equations. By means of the theory of partial differential in- equalities the author obtains the existence and asymptotic estimation of the solutions, involving the boundary and interior layer behavior, of the problems as described.This paper investigates the boundary value problems for a class of singularly perturbed nonlinear elliptic equations.
