An analysis of exponential kernel fractional difference operator for delta positivity

open access: yesNonlinear Engineering
Positivity analysis for a fractional difference operator including an exponential formula in its kernel has been examined. A composition of two fractional difference operators of order (ν,μ)\left(\nu ,\mu ) in the sense of Liouville–Caputo type operators

Parametric Fourier and Mellin transforms of power-constructible functions

open access: yesForum of Mathematics, Sigma
We enrich the class of power-constructible functions, introduced in [CCRS23], to a class $\mathcal {C}^{\mathcal {M,F}}$ of algebras of functions which contains all complex powers of subanalytic functions and their parametric Mellin and Fourier ...

Certain properties and characterizations of a novel family of bivariate 2D-q Hermite polynomials

open access: yesOpen Mathematics
This study presents a novel family of bivariate 2D-qq Hermite polynomials. We derive explicit forms and qq-partial differential equations and investigate numerical aspects associated with these polynomials.

A Sharp Double Inequality for the Inverse Tangent Function [PDF]

open access: yes, 2013
The inverse tangent function can be bounded by different inequalities, for example by Shafer's inequality. In this publication, we propose a new sharp double inequality, consisting of a lower and an upper bound, for the inverse tangent function.

Some implications of a new definition of the exponential function on time scales

open access: yes, 2010
We present a new approach to exponential functions on time scales and to timescale analogues of ordinary differential equations. We describe in detail the Cayley-exponential function and associated trigonometric and hyperbolic functions. We show that the

Coefficient estimates for some classes of functions associated with \(q\)-function theory

open access: yes, 2017
In this paper, for every $q\in(0,1)$, we obtain the Herglotz representation theorem and discuss the Bieberbach type problem for the class of $q$-convex functions of order $\alpha, 0\le ...
