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