Angular estimations of certain integral operators

Abstract

ABSTRACT. The object of the present paper is to derive some argument properties of certain integral operators. Our results contain some interesting corollaries as the special cases.

Argument Properties for a Class of Analytic Functions Involving Libera Transform

“…We mention that several authors have investigated the strongly star-like functions and the strongly convex functions (see [5][6][7][8][9][10][11][12][13][14][15][16][17][18]). In the present investigation we give some argument properties of analytic functions belonging to A, such that the images of these functions by the Libera transform have bounded arguments.…”
