Abstract:
We establish results on existence, non-existence, and
asymptotic behavior of ground state solutions for the
singular nonlinear elliptic problem
where
is a parameter,
,
not identically zero, is a locally Holder continuous function;
and
are continuous functions,
(possibly) singular in
; that is,
and either
or
as
.
The main purpose of this article is to complement the main
theorem in Porru and Vitolo [15], for the case
.
No monotonicity condition is imposed on f or g.
