Generalizations of Ostrowski type inequalities via Hermite polynomials

open access: yesJournal of Inequalities and Applications, 2020
We present new generalizations of the weighted Montgomery identity constructed by using the Hermite interpolating polynomial. The obtained identities are used to establish new generalizations of weighted Ostrowski type inequalities for differentiable ...

Identity-Type Functions and Polynomials [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
For a noncommuting product of functions, similar to convolutions, an “identity-type function” leaving a specific function invariant is defined. It is evaluated for any choice of function on which it acts by solving a functional equation. A closed-form representation for the identity-type function of(1+t)−b(b>0)is obtained, which is a solution of a ...

On rational functional identities

open access: yes, 2023
In this paper, we progress in the general study of rational functional identities in the setting of division rings. The main theorem in the paper states that the only additive maps $f$ and $g$ satisfying that $f(x)=-x^ng(x^{-1}) $, for $n=3$ or $4$, are ...

Reflection Identities of Harmonic Sums of Weight Four

open access: yesUniverse, 2019
In attempt to find a proper space of function expressing the eigenvalue of the color-singlet BFKL equation in N = 4 SYM, we consider an analytic continuation of harmonic sums from positive even integer values of the argument to the complex plane.

Generalized derivations acting on Lie ideals in prime rings and Banach algebras

open access: yesМатематичні Студії, 2023
Let $R$ be a prime ring and $L$ a non-central Lie ideal of $R.$ The purpose of this paper is to describe generalized derivations of $R$ satisfying some algebraic identities locally on $L.$ More precisely, we consider two generalized derivations $F_1$ and

Responses of Functional and Taxonomic Phytoplankton Diversity to Environmental Gradients in Subtropical and Tropical Reservoirs

open access: yesFrontiers in Environmental Science, 2022
Understanding the influence of environmental conditions on biodiversity is a major task in ecology. We investigated how phytoplankton taxonomic (TD) and functional (FD) diversities vary with environmental factors in eight subtropical and tropical ...

Combinatorial Sums and Identities associated with Functional Equations of Generating Functions for Fubini Type Polynomials [PDF]

open access: yes, 2023
Using generating functions with their functional equations method, a great number of novel combinatorial sums, formulas, and recurrence relation including Fubini type polynomials and numbers, Stirling type numbers, and Apostol type polynomials are given.

On generalization of refinement of Jensen’s inequality using Fink’s identity and Abel-Gontscharoff Green function

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we formulate new Abel-Gontscharoff type identities involving new Green functions for the ‘two-point right focal’ problem. We use Fink’s identity and a new Abel-Gontscharoff-type Green’s function for a ‘two-point right focal’ to generalize ...
