Asymptotics of orthogonal polynomials generated by a Geronimus perturbation of the Laguerre measure [PDF]

open access: yes, 2016
This paper deals with monic orthogonal polynomials generated by a Geronimus canonical spectral transformation of the Laguerre classical measure for x in [0,?), ?

A filtration on the ring of Laurent polynomials and representations of the general linear Lie algebra

open access: yes, 2021
We first present a filtration on the ring Ln of Laurent polynomials such that the direct sum decomposition of its associated graded ring grLn agrees with the direct sum decomposition of grLn, as a module over the complex general linear Lie algebra gl(n),

A standard form in (some) free fields: How to construct minimal linear representations

open access: yesOpen Mathematics, 2020
We describe a standard form for the elements in the universal field of fractions of free associative algebras (over a commutative field). It is a special version of the normal form provided by Cohn and Reutenauer and enables the use of linear algebra ...

Generic extensions and generic polynomials for linear algebraic groups [PDF]

open access: yesJournal of Algebra, 2016
We show the existence of and explicitly construct generic polynomials for various groups, over fields of positive characteristic. The methods we develop apply to a broad class of connected linear algebraic groups defined over finite fields satisfying certain conditions on cohomology.

Symbolic Analysis for Boundary Problems: From Rewriting to Parametrized Groebner Bases [PDF]

open access: yes, 2010
We review our algebraic framework for linear boundary problems (concentrating on ordinary differential equations). Its starting point is an appropriate algebraization of the domain of functions, which we have named integro-differential algebras.

Spectra of some algebras of entire functions of bounded type, generated by a sequence of polynomials

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2019
In this work, we investigate the properties of the topological algebra of entire functions of bounded type, generated by a countable set of homogeneous polynomials on a complex Banach space. Let $X$ be a complex Banach space. We consider a subalgebra $

On λ-linear functionals arising from p-adic integrals on Z p $\mathbb{Z}_{p}$

open access: yesAdvances in Difference Equations, 2021
The aim of this paper is to determine the λ-linear functionals sending any given polynomial p ( x ) $p(x)$ with coefficients in C p $\mathbb{C}_{p}$ to the p-adic invariant integral of P ( x ) $P(x)$ on Z p $\mathbb{Z}_{p}$ and also to that of P ( x 1 + ⋯

Solving Nonlinear Multi-Order Fractional Differential Equations Using Bernstein Polynomials

open access: yesIEEE Access, 2023
This paper introduces two novel methods for solving multi-order fractional differential equations using Bernstein polynomials. The first method, referred to as the fractional operational matrix of differentiation of Bernstein polynomials, is employed to ...

The complexity of some families of cycle-related graphs

open access: yesJournal of Taibah University for Science, 2017
In this paper, we derive new formulas for the number of spanning trees of a specific family of graphs – gear graphs, flower graphs, sun graphs and sphere graphs – using techniques from linear algebra, Chebyshev polynomials and matrix theory.
