We introduce a subclass of uniformly starlike and convex functions with negative coefficients defined by Sălăgean operator. In this paper, we obtain coefficient estimates, distortion theorems, closure theorems and radii of close-to-convexity, starlikeness, and convexity for functions belonging to this class. Several results for the modified Hadamard products of functions belonging to this class are obtained. Finally, distortion theorems for fractional calculus functions are also considered.

In this paper, we obtain Fekete-Szegö functional ∣ap+2 - μa2p+1∣ for functions of the class Mm,λb,p,q(g, φ). Sharp bounds for the Fekete-Szegö functional ∣ap+2 - μa2p+1∣ are obtained. [ABSTRACT FROM AUTHOR]
