摘要：

We consider positive solutions to the singular semilinear elliptic equation -Delta u = 1/u(gamma) + f (u), in bounded smooth domains, with zero Dirichlet boundary conditions. We provide some weak and strong maximum principles for the H-0(1)(Omega) part of the solution (the solution u generally does not belong to H-0(1)(Omega)), that allow to deduce symmetry and monotonicity properties of solutions, via the Moving Plane Method.
