We consider radial solutions of a general elliptic equation involving a weighted Laplace operator. We establish the uniqueness of the radial bound state solutions to
$ \mbox{div}\big(\mathsf A\, \nabla v\big)+\mathsf B\, f(v) = 0\, , \quad\lim\limits_{|x|\to+\infty}v(x) = 0, \quad x\in\mathbb R^n, ~~~~{(P)} $
$ n>2 $
, where
$ \mathsf A $
 and
$ \mathsf B $
 are two positive, radial, smooth functions defined on
$ \mathbb R^n\setminus\{0\} $
. We assume that the nonlinearity
$ f\in C(-c, c) $
,
$ 0<c\le\infty $
 is an odd function satisfying some convexity and growth conditions, and has a zero at
$ b>0 $
, is non positive and not identically 0 in
$ (0, b) $
, positive in
$ (b, c) $
, and is differentiable in
$ (0, c) $
.
Keywords: Uniqueness, weighted Laplace operator, bound states, semilinear, elliptic.
