摘要
This paper deals with a class of degenerate quasilinear elliptic equations of the form -div(a(x, u, del u) = g - div(f), where a(x, u, del u) is allowed to be degenerate with the unknown u. We prove existence of bounded solutions under some hypothesis on f and g. Moreover we prove that there exists a renormalized solution in the case where g is an element of L-1(Omega) and f is an element of (L-p'(Omega))(N). (C) 2010 Elsevier Ltd. All rights reserved.
