چکیده
|
In this paper, we study coposinormal composition operators and posinormal weighted composition operators on the hardy space h2 (d). we show that if wψ,ϕ is coposinormal on h2 (d), then ψ never vanishes on d also we prove that ϕ is univalent. moreover, we study the commutant of a coposinormal weighted composition operator.
