On generalizations of some fixed point theorems in semimetric spaces with triangle functions

Frontiers in Applied Mathematics and Statistics
In the present study, we prove generalizations of Banach, Kannan, Chatterjea, Ćirić-Reich-Rus fixed point theorems, as well as of the fixed point theorem for mapping contracting perimeters of triangles.

Complex Multivariate Montgomery Type Identity Leading to Complex Multivariate Ostrowski and Grüss Inequalities

Communications in Advanced Mathematical Sciences, 2019
We give a general complex multivariate Montgomery type identity which is a representation formula for a complex multivariate function. Using it we produce general tight complex multivariate high order Ostrowski and Grüss type inequalities.

Integral Operators on the Besov Spaces and Subclasses of Univalent Functions [PDF]

Sahand Communications in Mathematical Analysis, 2020
‎In this note, we study the integral operators $I_{g}^{\gamma, \alpha}$ and $J_{g}^{\gamma, \alpha}$ of an analytic function $g$ on convex and starlike functions of a complex order. Then, we investigate the same operators on $H^{\infty}$ and Besov spaces.

Complex small entire functions

Mathematics Open
Small functions were defined in complex analysis together with the notions of order of growth, lower order of growth, type of growth and lower type of growth. The set of small entire functions with respect to an entire function f is a [Formula: see text]-

Uniqueness of meromorphic functions sharing small functions in the k-punctured complex plane

AIMS Mathematics, 2020
The main purpose of this article is concerned with the uniqueness of meromorphic functions in the $k$-punctured complex plane $\Omega$ sharing five small functions with finite weights.

On close-to-convex functions of complex order

International Journal of Mathematics and Mathematical Sciences, 1990
The class S*(b) of starlike functions of complex order b was introduced and studied by M.K. Aouf and M.A. Nasr. The authors using the Ruscheweyh derivatives introduce the class K(b) of functions close-to-convex of complex order b, b≠0 and its ...

Complex Networks of Functions

, 2021
Functions correspond to one of the key concepts in mathematics and science, allowing the representation and modeling of several types of signals and systems. The present work develops an approach for characterizing the coverage and interrelationship between discrete signals that can be fitted by a set of reference functions, allowing the definition of ...

Coherent States with Complex Functions [PDF]

International Journal of Theoretical Physics, 2004
The canonical coherent states are expressed as infinite series in powers of a complex number $z$ in their infinite series version. In this article we present classes of coherent states by replacing this complex number $z$ by other choices, namely, iterates of a complex function, higher functions and elementary functions.
