Abstract

In this paper we study some properties of the torsion function with Robin boundary conditions. Here we write the shape derivative of the and norms, for , of the torsion function, seen as a functional on a bounded simply connected open set , and prove that the balls are critical shapes for these functionals, when the volume of is preserved.
