Abstract:
We consider the boundary-value problem
where
(
),
,
,
,
and the function
is
and
satisfies
These assumptions on
imply that the trivial solution
is the only solution
with
or
,
and if
then any solution
is {\em positive},
that is,
on
.
We prove that the set of nontrivial solutions
consists of a
curve of positive solutions in
,
with a parametrisation of the form
,
where
is a
function defined on
,
and
is a suitable weighted eigenvalue of the
-Laplacian
(
may be finite or
),
and
satisfies
We also show that for each
the solution
is globally asymptotically stable,
with respect to positive solutions
(in a suitable sense).
