Hao Zhang : Schatten class membership of commutators
Abstract:
Commutators are well-known as generalization of Hankel type operators. In this talk, we are concerned about the Schatten class membership of commutators involving nondegenerate singular integral operators. We describe their Schatten class membership in terms of Besov spaces. Our approach is based on the complex median method, which is an extension of Lerner’s median method and is applicable to complex-valued functions.
