A CERTAIN SUBCLASS OF MULTIVALENT FUNCTIONS WITH NEGATIVE COEFFICIENTS FOR OPERATORS ON HILBERT SPACE
Jae Ho Choi · Far East Journal of Mathematical Sciences (FJMS) · 2020
The main object of the present paper is to investigate some results concerning a sufficient and necessary condition, coefficient estimates and distortion theorem for the class $\mathcal{T}^{\lambda}_{p, \delta}(\alpha, A)$. Also, we consider several applications of the fractional calculus for operator on Hilbert space.
