In this paper, we shall show that the limiting absorption principle for thewave operator on the asymptotically Minkowski spacetime. This problem waspreviously considered by [A. Vasy, J. Spect. Theory, 10,439-461 , (2020)].Here, we employ a more transparent tool, the Mourre theory and removes anadditional condition which is imposed in his paper. Moreover, we also provethat the anti-Feynman propagator defined by G\'erard and Wrochna coincides withthe outgoing resolvent.
