Abstract:

In this paper, we construct a shape functional for p-torsional rigidity problems and prove that the optimal shape of this shape functional is a ball. Using a method of the shape derivative, we give an alternative proof of the overdetermined problem for p-torsional rigidity.

Key words: Shape optimiztion, Overdetermined problem, p-Torsional rigidity
