Abstract. In this paper we establish the uniqueness of radial solutions for a semipositone Dirichlet problem in an annulus, having a prescribed large number of nodal regions. Shooting method and Prüfer transformation are the main tools used in this work.

Palavras-chave : Semipositone; nonhomogeneous problem; uniqueness of sign hanging solution; weighted Dirichlet problem; nonlinear elliptic problem.
