On a Class of Spirallike Functions associated with a Fractional Calculus Operator

Abstract

Abstract. In this article, by making use of a linear multiplier fractional differential operator D δ,m λ , we introduce a new subclass of spiral-like functions. The main object is to provide some subordination results for functions in this class. We also find sufficient conditions for a function to be in the class and derive Fekete-Szegö inequalities.
