On a class of meromorphic Multiivalent functiions convoluted withi higher derivatiives of fractionali calculus operator

الملخص EN

The main goal of this paper is to study and discuss a new class of meromorphici "functions[ which are multivalent defined by [fractional calculus operators.

Coefficients iestimates , radiisi of satarlikeness , convexityi and closed-to-iconvexity are studied.

Also distortion iand closure theorems for the classi class ∑+b (ʎ, µ, ν, η, y, a, β) are considered.
