Abstract
Consider the problem(1) where , and an even integer. In this work we are interested in finding positive classical nonradial solutions of (1). We also consider the problem on the unit ball. We demonstrate the existence of a positive bounded solution for the range , and show that nonradial solutions exist for a specific range of p.
