The centralizer of the Laguerre polynomial set [PDF]

open access: greenRocky Mountain Journal of Mathematics, 1979
The set \(\pi\) of all simple polynomial sets with umbral product is a noncommutative group with the identity \(I=\{x^ n,\quad n=0,1,2,...\}.\) The authors have studied the characterization of the elements of the centralizer \(C_{\pi}(L^{\alpha})\) of the Laguerre polynomial set in the group \(\pi\). Four special cases have also been considered.

Hermite and Laguerre 2D polynomials

open access: bronzeJournal of Computational and Applied Mathematics, 2001
The Hermite \(2D\) polynomials \(H_{m,n} (U;x,y)\) and Laguerre \(2D\) polynomials \(L_{m,n} (U;z,\overline z)\) are defined as functions of two variables with an arbitrary \(2D\) matrix \(U\) as parameter. Their properties are discussed, explicit representations are given and recursion relations and generating functions for these polynomials are ...

Bounds for zeros of the Laguerre polynomials

open access: bronzeJournal of Approximation Theory, 2003
The author shows that the least and largest zeros \(x_1, x_n\) of the Laguerre polynomial \(L_n ^{(\alpha)}(x)\) satisfies \[ x_1 > s-r + {(s-r)^{2/3} \over 2r^{1/3}} \] \[ x_n < s+r + {(s+r)^{2/3} \over 2r^{1/3}} \] with \[ s=2n+ \alpha +1, \;r= \sqrt{4n^2 +(2n-1)(2 \alpha +2)} \] provided \(n\geq 7, \alpha \geq 8\).

Exceptional Laguerre Polynomials [PDF]

open access: yesStudies in Applied Mathematics, 2018
AbstractThe aim of this paper is to present the construction of exceptional Laguerre polynomials in a systematic way and to provide new asymptotic results on the location of the zeros. To describe the exceptional Laguerre polynomials, we associate them with two partitions.

Products of Laguerre Polynomials [PDF]

open access: yesMathematics of Computation, 1960
and, in particular, is symmetric in r, s, t. A closed formula has been obtained for Cry by Watson [41. We begin by obtaining the same formula by a very simple argument. In ? wce (lerive a simple recurrence relation suitable for rapidly generating the coefficients as needed when working with a high speed computing machine.

Laguerre polynomials of derivations [PDF]

open access: yesIsrael Journal of Mathematics, 2014
We introduce a 'grading switching' for arbitrary nonassociative algebras of prime characteristic p, aimed at producing a new grading of an algebra from a given one. We take inspiration from a fundamental tool in the classification theory of modular Lie algebras known as 'toral switching', which relies on a delicate adaptation of the exponential of a ...
