Coefficient estimates for some new classes of bi-Bazilevic functions of Ma-Minda type involving the Salagean integro-differential operator

Abstract

In this paper we introduce and investigate new classes of bi-Bazilevic functions of Ma-Minda type involving the Salagean integro-differential operator. Bounds of the rst three coefficients ∣a₂∣, ∣a₃∣ and ∣a₄∣ are given.

Key words: Bi-Bazilevic functions of Ma-Minda type, bi-univalent functions, Salagean integral and differential operator, coefficient bounds.
