Abstract:
We prove existence of radial solutions of
on the
exterior of the ball, of radius R, centered at the origin in
such that
if R>0 is sufficiently small.
We assume
is odd and there exists a
with f<0 on
,
f>0 on
with f sublinear
for large u, and
for large r with
.
We also prove nonexistence if R>0 is sufficiently large.
