On radial symmetry and its breaking in the Caffarelli-Kohn-Nirenberg type inequalities for p = 1

The main purpose of this article is to study the Caffarelli-Kohn-Nirenberg type inequalities (1.2) with p = 1. We show that symmetry breaking of the best constants occurs provided that a parameter |γ| is large enough. In the argument we effectively employ equivalence between the Caffarelli-Kohn-Nire...

Zusammenfassung:The main purpose of this article is to study the Caffarelli-Kohn-Nirenberg type inequalities (1.2) with p = 1. We show that symmetry breaking of the best constants occurs provided that a parameter |γ| is large enough. In the argument we effectively employ equivalence between the Caffarelli-Kohn-Nirenberg type inequalities with p = 1 and isoperimetric inequalities with weights.
