$m$-Symmetric functions, non-symmetric Macdonald polynomials and positivity conjectures [PDF]
We study the space, $R_m$, of $m$-symmetric functions consisting of polynomials that are symmetric in the variables $x_{m+1},x_{m+2},x_{m+3},\dots$ but have no special symmetry in the variables $x_1,\dots,x_m$.

Accelerating Materials Discovery: A Review of Machine Learning in X‐Ray Absorption Spectroscopy
Advanced Intelligent Systems, EarlyView.This review systematically details how machine learning transforms X‐ray absorption spectroscopy (XAS) analysis. It covers advanced deep learning architectures for structure‐spectra mapping and inverse tasks, while discussing key challenges like the simulation‐to‐reality gap.

, 2004 Multisymmetric polynomials are the $r$-fold diagonal invariants of the symmetric group ${\mathfrak{S}}_n$. Elementary multisymmetric polynomials are analogues of the elementary symmetric polynomials, in the multisymmetric setting.

Do Commodity Prices and Energy Markets Drive Asymmetric Volatility in Biodiversity Finance?
Business Strategy and the Environment, EarlyView.ABSTRACT This study examines symmetric and asymmetric volatility spillovers among biodiversity finance, commodity prices, and energy markets using daily data from 2019 to 2025. We apply the Diebold–Yilmaz time–domain connectedness model, Baruník–Křehlík frequency–domain decomposition, and an asymmetric spillover framework.

Elementary symmetric polynomials under the fixed point measure
We identify a surprising inequality satisfied by elementary symmetric polynomials under the action of the fixed point measure of a random permutation. Concretely, for any collection of $n$ non-negative real numbers $a_1, \dots, a_n \in \mathbb{R}_{\geq 0}$, we prove that \[ \frac{1}{n!} \sum_{π\in S_n} \left[\prod_{\{i:i=π(i)\}} a_i\right] \ge \frac ...

The Canadian Journal of Chemical Engineering, EarlyView.A perturbative Graetz model describes coupled heat and mass transfer in reactive Couette–Poiseuille flow between parallel plates. Viscous dissipation and heat of reaction produce a small temperature rise, which enhances Arrhenius reaction rates and modestly accelerates axial species conversion in the small‐Brinkman‐number regime.

Extrema of elementary symmetric polynomials of the eigenvalues of the matrix P∗KP+L
Linear Algebra and its Applications, 1974 AbstractThe paper describes extrema of elementary symmetric polynomials of mth order of the eigenvalues of the matrix P∗KP+L where P is an n by k matrix (n⩾k) and P∗ its conjugate transpose, such that P∗P=I; and K,L are Hermitian, positive- definite matrices of dimensions n by n, k by k, respectively.
