An existence result for a semipositone problem with a sign changing weight
Jaffar Ali, R. Shivaji · Abstract and Applied Analysis · 2006
We establish an existence result on positive solution for a class of reaction-diffusion equation with semipositone structure.In particular, our results apply to the diffusive logistic equation with a class of sign changing weight and constant yield harvesting.We establish the result via the method of subsuper solutions.
