Certain classes of multivalent functions with negative coefficients associated with a convolution structure
Making use of a convolution structure, we introduce a new class of
analytic functions
defined in the open unit disc and investigate its various
characteristics. Further we obtained distortion bounds, extreme
points and radii of close-to-convexity, starlikeness and convexity
for functions belonging to the class
$mathbb{T}^{p}_{g}(lambda,alpha, beta).
