Abstract.
In this paper we consider radially symmetric solutions of the nonlinear Dirichlet problem in
, where
is an annulus in
,
,
and
satisfies some appropriate conditions. We establish a priori estimates of radial solutions with
prescribed number of zeros. Moreover, when
, where
is odd and super-linear at infinity, using the uniqueness result due to Tanaka (2007), we verify that these solutions are non-degenerate and we prove that their radial Morse index is exactly
