### Abstract

Let S denote the class of analytic univalent functions in 𝔻:= {z ϵ ℂ: |z| < 1} normalized so that f z = z + ∑ n = 2 ∞ a n z n . $$f(z)=z+{\sum}_{n=2}^{\infty }{a}_n{z}^n.$$ Let C and S ∗ be the subclasses of S consisting of convex and starlike functions, respectively. For real α, the class M α of alpha-convex functions f ∈ S defined by
