Existence and uniqueness conditions of positive solutions to semilinear elliptic equations with double power nonlinearities
arXiv:0811.0946
Abstract
In this article we find the equivalent conditions to assure the existence and uniqueness of positive solutions to semilinear elliptic equations wih double power nonlinearities. As a bonus, we give a simpler proof of our former result that the uniqueness condition comes from the existence condition.
