Abstract
Let Cs(A, B) denote the class of functions f which are analytic in an open unit disc D = {z: z < 1} and satisfying the condition 2(zfâ€²(z))â€²/(f(z)f(z))â€² â‰º 1+Az/1+Bz, 1 â‰¤ B < A â‰¤ 1, z âˆˆ D. In this paper, we consider the class Ks* (A, B) consisting of analytic functions f and satisfying (zfâ€²(z))â€²/(g(z)g(z))â€² â‰º 1+Az/1+Bz, g âˆˆ Cs(A,B), 1 â‰¤ B < A â‰¤ 1, z âˆˆ D. The aims of paper are to determine coefficient estimates, distortion bounds and preserving property for a certain integral operator for the class Ks* (A, B).
