Abstract:
We consider positive solutions to the non-variational family of equations
where
,
b(x) is a given function, g is an increasing
nonlinearity with g(0)> 0 and
is a bounded smooth domain.
We introduce the definition of stability for non-variational problems and
establish existence and regularity results for stable solutions.
These results generalize the classical results obtained when
is a constant function making the problem variational after a suitable
transformation.
