本文对某些Fourier积分算子代数(包括严格伪凸域边界上的Toeplitz算子代数)定义了迹泛函,并证明了迹的消失刻画了这些代数中的算子.
Abstract In this paper a trace functional is defined for certain algebras of Fourier integral operators (including, for instance, the algebra of Toeplitz operators on the boundary of a strictly pseudoconvex domain) and it is shown that vanishing of this trace characterizes commutators in each of these algebras.
