Abstract:
It is well known that the sharp constant of the Sobolev inequality in the whole space is attained by the Talenti function, but not in bounded domains since a scale invariance is breaking. In this talk, we introduce a scale invariant form of the Sobolev inequality in the unit ball, and show that the sharp constant is attained by a Talenti like function.
