Point-evaluation functionals on algebras of symmetric functions on $(L_\infty)^2$

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2019
It is known that every continuous symmetric (invariant under the composition of its argument with each Lebesgue measurable bijection of $[0,1]$ that preserve the Lebesgue measure of measurable sets) polynomial on the Cartesian power of the complex Banach

Continuous block-symmetric polynomials of degree at most two on the space $(L_\infty)^2$

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2016
We introduce block-symmetric polynomials on $(L_\infty)^2$ and prove that every continuous block-symmetric polynomial of degree at most two on $(L_\infty)^2$ can be uniquely represented by some "elementary" block-symmetric polynomials.

q-Calculus as operational algebra; pp. 73–97 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2009
This second paper on operational calculus is a continuation of Ernst, T. q-Analogues of some operational formulas. Algebras Groups Geom., 2006, 23(4), 354–374. We find multiple q-analogues of formulas in Carlitz, L.

Some symmetric polynomial and related identities [PDF]

open access: yesریاضی و جامعه
In this paper, we study some symmetric polynomials and their properties. In addition to the elementary and complete symmetric polynomials, we consider the accumulative versions of these polynomials and using common combinatorial tools, particularly ...

A practical method for constructing a reflectionless potential with a given energy spectrum; pp. 358–377 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2016
A fully algebraic approach to constructing one-dimensional reflectionless potentials with any number (N) of bound states is described. A simple and easily applicable general formula is derived, using the methods of the theory of determinants.

Symmetric Polynomials in Free Associative Algebras—II

open access: yesMathematics, 2023
Let K⟨Xd⟩ be the free associative algebra of rank d≥2 over a field, K. In 1936, Wolf proved that the algebra of symmetric polynomials K⟨Xd⟩Sym(d) is infinitely generated.

Symmetric $*$-polynomials on $\mathbb C^n$

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2018
$*$-Polynomials are natural generalizations of usual polynomials between complex vector spaces. A $*$-polynomial is a function between complex vector spaces $X$ and $Y,$ which is a sum of so-called $(p,q)$-polynomials.

Elementary symmetric polynomials of increasing order [PDF]

open access: yesProbability Theory and Related Fields, 1988
The asymptotic behaviour of elementary symmetric polynomials \(S_ n^{(k)}\) of order k, based on n independent and identically distributed random variables \(X_ 1,...,X_ n\), is investigated for the case that both k and n get large. If \(k=o(n^{1/2})\), then the distribution function of a suitably normalized \(S_ n^{(k)}\) is shown to converge to a ...

Counting strings over $\mathbb{Z}2^d$ with Given Elementary Symmetric Function Evaluations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
Let $\alpha$ be a string over $\mathbb{Z}_q$, where $q = 2^d$. The $j$-th elementary symmetric function evaluated at $\alpha$ is denoted $e_j(\alpha)$ . We study the cardinalities $S_q(m;\mathcal{T} _1,\mathcal{T} _2,\ldots,\mathcal{T} _t)$ of the set of

Vanishing Results for Hall-Littlewood Polynomials [PDF]

open access: yes, 2012
It is well-known that if one integrates a Schur function indexed by a partition λ over the symplectic (resp. orthogonal) group, the integral vanishes unless all parts of λ have even multiplicity (resp. all parts of λ are even).
