Jingyao Tu,Zhenhua Duan,Cong Tian,Nan Zhang,Ying Wu a self-adjoint realization of the Klein–Gordon operator. All these constructions find an important application in Quantum Field Theory on curved spacetimes. The Feynman propagator yields the expectation values of time-ordered products of fields between the “in vacuum” and the “out vacuum”—the basic
