Recently, the class Pa (A.B) of analytic functions in the unit disk was studied. In this paper, we shall define the subclass Pci(A, B) of Pix(A, B) and a class 1%, ..(A, B) of analytic functions in the unit disk. The object of the present paper is to show the interesting coefficient estimates for the classes Pm(A, b), &.(A, B), PR (A, O) and (A, 0). oc 517.52 Series and sequences
