FRACTIONAL DERIVATIVE OPERATORS ASSOCIATED WITH SOME SUBCLASSES OF STARLIKE FUNCTIONS
(ELMERGIB UNIVERSITY, 2017-12)
In this paper we introduce new subclasses of starlike functions in the open unit disk by using fractional derivative operator. We obtain coefficient inequalities and distortion theorems for functions belonging to these ...
DIFFERENTIAL SANDWICH THEOREMS FOR P-VALENT FUNCTIONS DEFINED BY CONVOLUTION INVOLVING CERTAIN FRACTIONAL DERIVATIVE OPERATOR
(ELMERGIB UNIVERSITY, 2017-06)
In the present paper we derive some subordination and superordination results for p-valent functions in the open unit disk defined by convolution involving certain fractional derivative operator. Relevant connections of ...
