Abstract:
This article concerns the existence of positive solutions to the
nonlinear elliptic system involving critical Hardy-Sobolev exponent
where
and
is a
bounded domain in
,
,
,
,
and
.
Let
be a linear subspace of
such that
, and
be the orthogonal
projection on
with respect to the Euclidean structure.
We consider mainly the case when
and
.
We show that there exists
such that the system above
possesses at least one positive solution for
provided that at each point
the principal curvatures of
at
are non-positive,
but not all vanish.
