Sažetak
Making use of a convolution structure, we introduce a new class of
analytic functions $\mathbb{T}^{p}_{g}(\lambda,\alpha, \beta, )$
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
$\mathbb{T}^{p}_{g}(\lambda,\alpha, \beta).$
Ključne riječi
