Abstract: In this paper, a class of the singularly perturbed Robin boundary value problem for elliptic equation is considered. Under suitable conditions, the existence, uniqueness and asymptotic behavior of the generalized solution for the problems were studied by means of the theory of differential inequalities, obtaining the uniformly valid asymptotic expansion of the solution.

Key words: elliptic equation, Robin problem, singular perturbation, generalized solution 
