Certain New Subclass of Multivalent Q-Starlike Functions Associated with Q-Symmetric Calculus
Fractal and Fractional, 2022 In our present investigation, we extend the idea of q-symmetric derivative operators to multivalent functions and then define a new subclass of multivalent q-starlike functions.

Subclasses of meromorphically multivalent functions defined by a differential operator
Computers and Mathematics With Applications, 2011 In this paper we introduce and study two new subclasses Σλμmp(α,β) and Σλμmp+(α,β) of meromorphically multivalent functions which are defined by means of a new differential operator.

Marx–Strohhäcker theorem for multivalent functions
Afrika Matematika, 2021Some differential implications of classical Marx-Strohhäcker theorem are extended for multivalent functions. These results are also generalized for functions with fixed second coefficient by using the theory of first order differential subordination which in turn, corrects the results of Selvaraj and Stelin [On multivalent functions associated with ...

On Nonsmooth Multivalent Guiding Functions
Differential Equations, 2003The method of guiding functions developed by Krasnosel'skii, Perov, Bobylev, and others is one of the most efficient tools for establishing the existence of periodic oscillations. In the framework of this method, the guiding potentials are usually assumed to be continuously differentiable, which is restrictive for application in many cases.

1994
The class of multivalent functions is an important one in complex analysis. They occur for example in the proof of De Branges' theorem which, in 1985, settled the long-standing Bieberbach conjecture. The second edition of Professor Hayman's celebrated book contains a full and self-contained proof of this result, with a chapter devoted to it.

BMOA and multivalent functions
Complex Variables, Theory and Application: An International Journal, 1997In this paper, we discuss the relation between BMOA (or Hardy-Orlicz Space HBa) and areally mean p-valent functions A(p), some growth estimates of f'/ff (n) for f∊A(p) are given; we find also some relations between A(p) and the class of normalization univalent functions S; Finally, we obtain a quantitative estimate on integral means of |f′|λ for f∊A(p)
