Abstract:
In this article, we study the problem
in the framework of weighted Sobolev spaces, with
unbounded function on u. The main contribution of our work is to
prove the existence of a renormalized solution without the sign
condition and the coercivity condition on
. The
critical growth condition on
is with respect to
Du and no growth condition with respect to u.
The second term f belongs to
, and
.
