摘要
In this paper we study a Dirichlet problem for an elliptic equation with degenerate coercivity and a singular lower order term with natural growth with respect to the gradient. The model problem is [GRAPHICS] where Omega is an open bounded set of R-N N >= 3 and p, theta > 0. The source f is a positive function belonging to some Lebesgue space. We will show that, even if the lower order term is singular, it has some regularizing effects on the solutions, when p > theta - 1 and theta < 2.
