Abstract
The purpose of this work is to study the following singular problem:
where
,
be a bounded smooth domain,
is a positive parameter,
such that
and
where
and r is the homogeneity degree of the function f. Under appropriate assumptions on the function f, we employ the method of Nehari manifold combined with the fibering maps in order to show the existence of
such that for all
, problem
has at least two positives solutions.
