摘要：

In this paper, we study coposinormal composition operators and posinormal weighted composition operators on the Hardy space H-2(D). We show that if W-psi,W-phi is coposinormal on H-2(D), then psi never vanishes on D also we prove that phi is univalent. Moreover, we study the commutant of a coposinormal weighted composition operator.
