| Abstract: | A necessary and sufficient condition is given that conjugate composite operatorsis subnormal in functional Hilbert space. The main result of Cowen is extended. Moreover,this paperhas also discussed that the subnormality of some composite operators in Hardy space H2 (D) andBergman space L(D). |
