摘要: In this paper, Dirichlet problem for second order quasi-linear elliptic equation with a small parameter at highest derivatives is studied. In case degenerate equation has no singular point and parameter e is sufficiently small, the existence and uniqueness of solution are proved, and the uniformly valid asymptotic solution is derived on the entire domain
