摘要: Generalized Anti-Wick operators are introduced as a class of pseudodifferential which depend on symbol and two different window functions. Using symbols in Sobolev spaces with negative smoothness and windows so-called modulation spaces, we derive new conditions for the boundedness L 2 such their membership the Schatten classes. These results extend refine contained [20], [10], [5], [4], [14].
