On a subclass of the generalized janowski type functions of complex order
Özet
In this paper, we introduce the class ?R? b (?, ?, ?, A,B) of generalized Janowski type functions of complex order defined by using the Ruscheweyh derivative operator in the open unit disc D = {z ? ?: |z| < 1}. The bound for the n-th coefficient and subordination relation are obtained for the functions belonging to this class. Some consequences of our main theorems are same as the results obtained in the earlier studies. © 2020, Hacettepe University. All rights reserved.

AN INVESTIGATION ON GEOMETRIC PROPERTIES OF ANALYTIC FUNCTIONS WITH POSITIVE AND NEGATIVE COEFFICIENTS EXPRESSED BY HYPERGEOMETRIC FUNCTIONS
Akyar, Alaattin; Mert, Oya; Yıldız, İsmet (Honam Mathematical Soc, 2022)This paper aims to investigate characterizations on parameters k(1), k(2), k(3), k(4), k(5), l(1), l(2), l(3), and l(4) to find relation between the class of H(k, l, m, n, o) hypergeometric functions defined by F-5(4) [(l1, ... -
On a p-ADIC interpolating function for the generalized genocchi numbers and its behaviour at s = 0
Araci, Serkan; Şen, Erdoğan (Charles Babbage Res Ctr, 2015)In this work, we consider the generalized Genocchi numbers and polynomials. However, we introduce analytic interpolating function for the generalized Genocchi numbers attached to chi at negative integers in complex plane ...
