Generating functions for generalized Stirling type numbers, Array type polynomials, Eulerian type polynomials and their applications [PDF]

open access: yesFixed Point Theory and Applications, 2011
The first aim of this paper is to construct new generating functions for the generalized λ-Stirling type numbers of the second kind, generalized array type polynomials and generalized Eulerian type polynomials and numbers.

Functional equations from generating functions: a novel approach to deriving identities for the Bernstein basis functions [PDF]

open access: yesFixed Point Theory and Applications, 2011
The main aim of this paper is to provide a novel approach to deriving identities for the Bernstein polynomials using functional equations. We derive various functional equations and differential equations using generating functions.

On the Zeros of Polynomials with Restricted Coefficients

open access: yesAnnales Mathematicae Silesianae, 2023
Let P(z)=∑j=0najzjP\left( z \right) = \sum\nolimits_{j = 0}^n {{a_j}{z^j}} be a polynomial of degree n such that an ≥ an−1 ≥ . . . ≥ a1 ≥ a0 ≥ 0. Then according to Eneström-Kakeya theorem all the zeros of P (z) lie in |z| ≤ 1.

A Cauchy-type generalization of Flett's theorem

open access: yesDemonstratio Mathematica, 2021
We prove a Cauchy-type generalization of Flett’s theorem and note its geometric interpretations. Several other mean value theorems extending further the result, which involve both real and complex functions, are also proved.

Paatero’s V(k) space II

open access: yesConcrete Operators, 2022
In this article we continue our investigation of the Paatero space. We prove that the intersection of every Paatero class V(k) with every Hardy space Hp is closed in that Hp and associate singular continuous measures to elements of V(k).

More on zeros and approximation of the Ising partition function

open access: yesForum of Mathematics, Sigma, 2021
We consider the problem of computing the partition function $\sum _x e^{f(x)}$ , where $f: \{-1, 1\}^n \longrightarrow {\mathbb R}$ is a quadratic or cubic polynomial on the Boolean cube $\{-1, 1\}^n$ .

Starlike and convexity properties of q-Bessel-Struve functions

open access: yesDemonstratio Mathematica, 2022
This paper introduces three different normalization associated with the second and third q-Bessel-Struve functions. We use Hadamard factorizations to determine the radii of starlike and convexity of these functions.

Numerical comparison of Caputo and Conformable derivatives of time fractional Burgers-Fisher equation

open access: yesResults in Physics, 2021
In this paper, the sub-equation method is used to obtain new types of complex traveling wave solutions of the time-fractional Burgers-Fisher equation. In this work is to compare the exact complex traveling wave solutions of new types and the numerical ...

Remarks to a theorem of Sinclair and Vaaler

open access: yes, 2020
Sinclair and Vaaler in [6] Theorem 1.2 found sufficient conditions, nonlinear in the coefficients depending on a parameter p 1 , for self-inversive polynomials to have all their zeros on the unit circle.
