Abstract:
This paper shows the existence of nontrivial weak
solutions for the quasilinear elliptic equation
in
. Here
is a positive continuous
potential bounded away from zero and
is a nonlinear term
of subcritical type.
Using minimax methods, we show the existence of a nontrivial solution
in
and then show that it
decays to zero at infinity when
.
