摘要
In this paper, we prove existence and regularity results for solutions of some nonlinear Dirichlet problems for an elliptic equation defined by a degenerate coercive operator and a singular right-hand side {-div(a(x,u, del u) = f/u(gamma) in Omega, u = 0 on partial derivative Omega, (1) where Omega is bounded open subset of R-N (N >= 2), gamma > 0 and f is a non-negative function that belongs to some Lebesgue space.
