Let A p n be the class of functions f z given by f z = z p + a p + n z p + n + a p + n + 1 z p + n + 1 + ⋯ which are analytic in the open unit disk U . For f z ∈ A p n , new integral operators O − j f z and O j f z j = 0 , 1 , 2 , ⋯ . are considered. The operators O − j f z and O j f z satisfy O j O − j f z = O − j O j f z = f z and O − j ∗
