Convex and Starlike Functions Defined on the Subclass of the Class of the Univalent Functions S with Order 2(- r)
Yıldız, İsmet; Mert, Oya; Akyar, Alaattin (Univ Maragheh, 2022)In this paper, some conditions have been improved so that the function g(z) is defined as g(z) = 1+ Sigma(infinity)(k >= 2) alpha n+k(zn+k), which is analytic in unit disk U, can be in more specific subclasses of the S ... -
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, ... -
SOME CONDITIONS ON STARLIKE AND CLOSE TO CONVEX FUNCTIONS
Yıldız, İsmet; Şahin, Hasan; Mert, Oya (Vinca Inst Nuclear Sci, 2022)Many mathematical concepts are explained when viewed through complex function theory. We are here basically concerned with the form f(z) = a(0) + a(1)z + a(2)z(2) +.... f(z) is an element of A, f(z) = z + Sigma(infinity) ...
