Quantum graphs whose spectra mimic the zeros of the Riemann zeta function [PDF]
One of the most famous problems in mathematics is the Riemann hypothesis: that the non-trivial zeros of the Riemann zeta function lie on a line in the complex plane.

Factorization theorems for classical group characters, with applications to alternating sign matrices and plane partitions [PDF]
We show that, for a certain class of partitions and an even number of variables of which half are reciprocals of the other half, Schur polynomials can be factorized into products of odd and even orthogonal characters.

This review discusses the use of Surface‐Enhanced Raman Spectroscopy (SERS) combined with Artificial Intelligence (AI) for detecting antimicrobial resistance (AMR). Various SERS studies used with AI techniques, including machine learning and deep learning, are analyzed for their advantages and limitations.

The RRSI (Right Region for Shading Inequalities)
Mathematics is often perceived as a difficult subject, which may discourage some people from learning it. Calculus is a branch of Mathematics that requires prior knowledge of pre-calculus. One topic in pre-calculus is solving a system of inequalities by

Young students’ understanding of mathematical equivalence across different schools in South Africa
Background: Mathematical equivalence is a critical element of arithmetic understanding and a key component of algebraic thinking which is necessary for success in all levels of mathematics. Research studies continue to highlight misconceptions related to

Alternating Sign Pentagons and Magog Pentagons [PDF]
Alternating sign triangles have been introduced by Ayyer, Behrend and Fischer in 2016 and it was proven that there is the same number of alternating sign triangles with $n$ rows as there is of $n\times n$ alternating sign matrices. Later on Fischer gave a refined enumeration of alternating sign triangles with respect to a statistic $\rho$, having the ...

List homomorphisms to separable signed graphs [PDF]
The complexity of the list homomorphism problem for signed graphs appears difficult to classify. Existing results focus on special classes of signed graphs, such as trees and reflexive signed graphs. Irreflexive signed graphs are in a certain sense the heart of the problem, as noted by a recent paper of Kim and Siggers.

On arithmetic and asymptotic properties of up-down numbers [PDF]
Let $\sigma=(\sigma_1,..., \sigma_N)$, where $\sigma_i =\pm 1$, and let $C(\sigma)$ denote the number of permutations $\pi$ of $1,2,..., N+1,$ whose up-down signature $\mathrm{sign}(\pi(i+1)-\pi(i))=\sigma_i$, for $i=1,...,N$.
