Bohr-type inequalities of analytic functions. [PDF]

open access: yesJ Inequal Appl, 2018
In this paper, we investigate the Bohr-type radii for several different forms of Bohr-type inequalities of analytic functions in the unit disk, we also investigate the Bohr-type radius of the alternating series associated with the Taylor series of ...

Normality of Composite Analytic Functions and Sharing an Analytic Function [PDF]

open access: yesFixed Point Theory and Applications, 2010
A result of Hinchliffe (2003) is extended to transcendental entire function, and an alternative proof is given in this paper. Our main result is as follows: let be an analytic function, a family of analytic functions in a domain , and a ...

On Pseudo-Analytic Functions [PDF]

open access: bronzeNagoya Mathematical Journal, 1957
Many of the properties of analytic functions can be proved in a purely topological manner, so that such properties are then valid for the larger class of functions which are topologically equivalent to analytic functions. The importance of such functions has been recognized fairly recently, particularly in the theory of partial differential equations ...

Sufficient Conditions for a New Class of Polynomial Analytic Functions of Reciprocal Order alpha [PDF]

open access: yesMathematics Interdisciplinary Research, 2017
In this paper, we consider a new class of analytic functions in the unit disk using polynomials of order alpha. We give some sufficient conditions for functions belonging to thisclass.

q-analytic functions, fractals and generalized analytic functions [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2014
We introduce a new class of complex functions of complex argument which we call q-analytic functions. These functions satisfy q-Cauchy–Riemann equations and have real and imaginary parts as q-harmonic functions. We show that q-analytic functions are not the analytic functions.

Approximation of Analytic Functions by Kummer Functions

open access: yesJournal of Inequalities and Applications, 2010
We solve the inhomogeneous Kummer differential equation of the form and apply this result to the proof of a local Hyers-Ulam stability of the Kummer differential equation in a special class of analytic functions.
