Existence of a positive solution for a-Laplacian semipositone problem
Boundary Value Problems volume 2005, Article number: 576572 (2005)
We consider the boundary value problem in satisfying on, where on, is a parameter, is a bounded domain in with boundary, and for. Here, is a nondecreasing function for some satisfying (semipositone). We establish a range of for which the above problem has a positive solution when satisfies certain additional conditions. We employ the method of subsuper solutions to obtain the result.
