Uniqueness of positive radial solutions for Dirichlet problems on annular domains

This paper deals with the uniqueness of positive radial solutions to Dirichlet problems on annular domains in Rn, n 3. As an application we can obtain the results to equation u +up −α1u−α0 = 0, where p >1, α1 0, α0 0 and α1 + α0 > 0. © 2007 Elsevier Inc. All rights reserved.
