On a differential subordination and superordination of a new class of meromorphic functions

open access: yesLe Matematiche, 2014
In this paper, we investigate differential subordination and superordination properties of a new class of meromorphic analytic functions in the punctured unit disc.We derive some sandwich theorems.

On Certain Subclasses of Analytic Functions Associated with a Symmetric q-Differential Operator

open access: yesMathematics
This paper explores a class of analytic functions defined in the open unit disk by means of a symmetric q-differential operator. In the first part, we derive sufficient conditions for functions to belong to a subclass associated with this operator, using

Ulam stability for fractional differential equations in the sense of Caputo operator [PDF]

open access: yes, 2012
In this paper, we consider the Hyers-Ulam stability for the following fractional differential equations, in the sense ofcomplex Caputo fractional derivative defined, in the unit disk: cDßzf(z)=G(f(z), cDázf(z),zf‘(z);z ...
