Abstract:
Let
be a bounded domain in
with smooth boundary, and
let
be points in
.
We are concerned with the singular stationary non-homogenous
Kuramoto-Sivashinsky equation
where f is a function that depends only the spatial variable. We
use a nonlinear domain decomposition method to give sufficient
conditions for the existence of a positive weak solution satisfying
the Dirichlet-like boundary conditions
,
and being
singular at each
as the parameters
and
tend to 0. An analogous problem in two-dimensions was
considered in [2] under condition (A1) below. However we do
not assume that condition.
