Abstract:
We consider the elliptic equation
in a region
,
where f is a positive continuous
function satisfying
Motivated by the thin film equations, a solution
is said to be a point
rupture solution if for some
,
and
in
.
Our main
result is a sufficient condition on f for the existence of radial point
rupture solutions.
