摘要
In this article we study nonnegative solutions of quasilinear equation model of which is -Delta(p)u + V(x)f(u) = h(x)vertical bar del(u)vertical bar(p-1) + g(x), p > 1. Under the natural assumptions on the functions f, V, h and g we prove the Harnack inequality with constant independent of the solution. In the case g(x) equivalent to V(x) we obtain an analogue of the well known Kilpelainen-Maly sub-bound.
