[HTML][HTML] On a generalization of uniformly convex and related functions

KI Noor - Computers & Mathematics with Applications, 2011 - Elsevier
In this paper, we define and study some subclasses of analytic functions by using the
concept of k-uniformly convexity. Several interesting properties, coefficients and radius …

Some properties of a generalized class of analytic functions related with Janowski functions

M Arif, KI Noor, M Raza, W Haq - Abstract and applied analysis, 2012 - Wiley Online Library
We define a class T ̃ k [A, B, α, ρ] of analytic functions by using Janowski's functions which
generalizes a number of classes studied earlier such as the class of strongly close‐to …
