ABSTRACT

In this paper we study the existence of solutions for quasilinear degenerated elliptic operators A(u) +g(x,u, \~/ u) = f  , where A  is a Leray-Lions operator from   1,p
W 0 (_O_,w)  into its dual, while g(x,s,q)  is a nonlinear term which has a growth condition with respect to q  and no growth with respect to s  , but it satisfies a sign condition on s  . The right hand side f  is assumed to belong either to   -1,p'    *
W     (_O_,w  )  or to  1
L (_O_)  .

Key words: weighted Sobolev spaces, Hardy inequality, quasilinear degenerated elliptic operators, truncations.
