Let M?B(H) be a countable decomposable properly infinite von Neumann algebra with a faithful normal semifinite tracial weight τ where B(H) is the set of all bounded linear operators on Hilbert space H.The main purpose of this article is to introduce generalized weak wave operators ■,generalized weak abelian wave operators■ and generalized stationary wave operators U±in M and then to explore the relation among ■,U± and generalized wave operators W±.
