Abstract:
This article concerns the existence of positive solutions
of semilinear elliptic system
where
is a bounded
domain with a smooth boundary
and
is a
positive parameter.
are sign-changing
functions.
are continuous with
,
.
By applying Leray-Schauder fixed point theorem,
we establish the existence of positive solutions for
sufficiently small.
