Abstract
ADUEN, HUGO and HERRON, SIGIFREDO. On the uniqueness of sign-changing solutions to a semipositone problem in annuli. Integración - UIS [online]. 2016, vol.34, n.2, pp.207-224. ISSN 0120-419X. https://doi.org/10.18273/revint.v34n2-2016007.
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.
Keywords : Semipositone; nonhomogeneous problem; uniqueness of sign hanging solution; weighted Dirichlet problem; nonlinear elliptic problem.
