Boundedness of Classical Calderón–Zygmund Convolution Operators on Flag Besov Spaces
摘要
It is well known that the classical Calderón-Zygmund convolution operators are bounded on the classical Besov spaces. A surprising result is that the operators are also bounded on the product Hardy spaces. The key idea is that the cancellation condition plays a crucial role. In this paper, we will prove that the classical Calderón-Zygmund convolution operators are bounded on the flag Besov spaces on the Euclidean space.
