Abstract
We are concerned with the following PDE: ,
in
,
, on
, where
is a bounded domain of
, and
is a given function. We provide a complete description of the loss of compactness of the equation under the assumption that K is strictly decreasing in the outward normal direction on
and flat near its critical points. As product, we prove an existence result through an Euler–Poincaré characteristic argument.
