Abstract

In this paper, we investigate certain subclasses of analytic functions defined by generalized differential operators involving binomial series. Also, we obtain coefficient estimates involving of the nonhomogeneous Cauchy-Euler differential equation of order r. [ABSTRACT FROM AUTHOR]

Abstract

Making use of a multiplier transformation, we introduce a new class of complex valued harmonic functions which are orientation preserving and univalent in the open unit disk U. Relevant connections of the results presented here with various known results are briefly indicated. [ABSTRACT FROM AUTHOR]
