摘要：
In this paper we study the existence and regularity of solutions to the following singular problem rS iota -div ( a ( x, u ) |del u | p - 2 del u ) + | u | s - 1 u = h ( u ) f in Omega u >= 0 in Omega (0.1) u = 0 on partial derivative Omega, proving that the lower order term u | u | s - 1 has some regularizing effects on the solutions in the case of an elliptic operator with degenerate coercivity.
