A Subclass of Multivalent Janowski Type q-Starlike Functions and Its Consequences

Symmetry, 2021
In this article, by utilizing the theory of quantum (or q-) calculus, we define a new subclass of analytic and multivalent (or p-valent) functions class Ap, where class Ap is invariant (or symmetric) under rotations.

Sufficient Conditions for Subordination of Multivalent Functions

Journal of Inequalities and Applications, 2008
The authors investigate various subordination results for some subclasses of analytic functions in the unit disc. We obtain some sufficient conditions for multivalent close-to-starlikeness.

Integral means of certain multivalent functions

International Journal of Mathematics and Mathematical Sciences, 2006
For analytic and multivalent functions f(z) and p(z) in the open unit disk U, a subordination theorem due to Littlewood (1925) which was called the integral mean is applied. Some simple examples for our results are also considered.
