Singular polynomials from orbit spaces [PDF]

open access: yes, 2012
We consider the polynomial representation S(V*) of the rational Cherednik algebra H_c(W) associated to a finite Coxeter group W at constant parameter c.

QUASI-EXACTLY SOLVABLE SCHRÖDINGER EQUATIONS, SYMMETRIC POLYNOMIALS AND FUNCTIONAL BETHE ANSATZ METHOD

open access: yesActa Polytechnica, 2018
For applications to quasi-exactly solvable Schrödinger equations in quantum mechanics, we consider the general conditions that have to be satisfied by the coefficients of a second-order differential equation with at most k + 1 singular points in order ...

q-Differential equations for q-classical polynomials and q-Jacobi-Stirling numbers [PDF]

open access: yes, 2016
We introduce, characterise and provide a combinatorial interpretation for the so-called q-Jacobi–Stirling numbers. This study is motivated by their key role in the (reciprocal) expansion of any power of a second order q-differential operator having the

Scattering amplitudes for all masses and spins

open access: yesJournal of High Energy Physics, 2021
We introduce a formalism for describing four-dimensional scattering amplitudes for particles of any mass and spin. This naturally extends the familiar spinor-helicity formalism for massless particles to one where these variables carry an extra SU(2 ...

The elementary symmetric functions of a reciprocal polynomial sequence [PDF]

open access: yesComptes Rendus. Mathématique, 2014
Erdös and Niven proved in 1946 that for any positive integers m and d , there are at most finitely many integers n for which at least one of the elementary symmetric functions of

On a conjecture for balanced symmetric Boolean functions

open access: yesJournal of Mathematical Cryptology, 2009
We give some results towards the conjecture that are the only nonlinear balanced elementary symmetric polynomials over GF(2), where t and are any positive integers and X(d, n) = Σ1 ...

Unusual square roots in the ghost-free theory of massive gravity

open access: yesJournal of High Energy Physics, 2017
A crucial building block of the ghost free massive gravity is the square root function of a matrix. This is a problematic entity from the viewpoint of existence and uniqueness properties. We accurately describe the freedom of choosing a square root of a (

Clifford-symmetric polynomials [PDF]

open access: yes, 2023
Based on the NilHecke algebra $\mathsf{NH}_n$, the odd NilHecke algebra developed by Ellis, Khovanov and Lauda and Kang, Kashiwara and Tsuchioka's quiver Hecke superalgebra, we develop the Clifford Hecke superalgebra $\mathsf{NH}\mathfrak{C}_n$ as ...

Dealing with ghost-free massive gravity without explicit square roots of matrices

open access: yesPhysics Letters B, 2017
In this paper we entertain a simple idea that the action of ghost free massive gravity (in metric formulation) depends not on the full structure of the square root of a matrix but rather on its invariants given by the elementary symmetric polynomials of ...

Elementary Symmetric Polynomials in Numbers of Modulus 1

open access: yesCanadian Journal of Mathematics, 2002
AbstractWe describe the set of numbersσk(z1,…,zn+1), wherez1,…,zn+1are complex numbers of modulus 1 for whichz1z2…zn+1= 1, andσkdenotes thek-th elementary symmetric polynomial. Consequently, we give sharp constraints on the coefficients of a complex polynomial all of whose roots are of the same modulus.
