Abstract:
In this article we analyze the exact boundary behavior of
solutions to the singular nonlinear Dirichlet problem
where
is a bounded domain with smooth
boundary in
,
,
,
,
,
,
is decreasing on
for some
,
for some
,
is positive in
,
but may be vanishing or
singular on the boundary. We show that
does not affect the first expansion of classical solutions near the
boundary.
