Hm. Srivastava et Mk. Aouf, SOME APPLICATIONS OF FRACTIONAL CALCULUS OPERATORS TO CERTAIN SUBCLASSES OF PRESTARLIKE FUNCTIONS WITH NEGATIVE COEFFICIENTS, Computers & mathematics with applications, 30(1), 1995, pp. 53-61
The object of the present paper is to prove various distortion theorem
s for the fractional calculus of functions in the subclasses R[alpha,
beta] and C[alpha, beta] consisting of prestarlike acid normalized ana
lytic functions with negative coefficients. Furthermore, distortion th
eorems involving a generalized fractional integral operator for functi
ons in the subclasses R[alpha, beta] and C[alpha, beta] are given.
