Starlike and Prestarlike Hypergeometric Functions

SIAM Journal on Mathematical Analysis, 1984
A linear operator is defined which acts on an analytic function in the open unit disk by forming its Hadamard product with an incomplete beta function. The operator is shown to be convenient in discussing starlike, convex, and prestarlike functions. It is applied to the study of certain classes of hypergeometric functions which constitute dense subsets

Certain Results on Starlike and Parabolic Starlike Functions

International Journal of Open Problems in Computer Science and Mathematics, 2015
Using the technique of differential subordination, we obtain certain results for starlike and parabolic starlike functions involving the differential operator zf ′(z) f(z) ( 1 + α zf ′′(z) f ′(z) ) . We study the above operator for multivalent functions and also conclude some results for univalent functions.

Starlikeness of the Gaussian hypergeometric functions

Complex Variables and Elliptic Equations, 2010
In this article, we derive conditions on the parameters a, b, c so that the function zF(a, b; c; z) is starlike in 𝔻, where F(a, b; c; z) denotes the classical hypergeometric function. We give some consequences of our results including some mapping properties of convolution operator.
