Fusion Systems on Sylow $3$-subgroups of Fischer and Monster sporadic groups: I

Pete Gautam ยท 2026

We classify all corefree fusion systems on a Sylow $3$-subgroup of the sporadic groups $\mathrm{Fi}_{22}$, $\mathrm{Fi}_{23}$ and $\mathrm{B}$. We show that the $3$-group in each case does not supportโ€ฆ

Relations between higher level Hurwitz class numbers

Ngoc Trinh Le ยท 2026

We connect generalizations of the classical Hurwitz class numbers coming from two different frameworks: one introduced by Pei and Wang, arising from the generalized Cohen--Eisenstein series, and anothโ€ฆ

Non-vanishing of the $p$-adic constant for mock modular forms associated to a newform with real Fourier coefficients

Ryota Tajima ยท 2026

Let $F^{+}$ be a mock modular form associated to a normalized newform $g$. K. Bringmann et. al. obtained a $p$-adic modular form starting from $F^{+}$ by adding a suitable linear combination of Eichleโ€ฆ

Eta-products, Eichler integrals, and the level-8 Apery limit

Alex Shvets ยท 2026

We give an independent eta-product derivation of the level-8 Apery limit lim B_n^{(8)}/s_n = (7/32) zeta(3), where s_n = sum_{k=0}^n C(n,k)^2 C(2k,n)^2 and B_n^{(8)} is the rational companion sequenceโ€ฆ

Normed lattices majorizing in their norm completions

Eugene Bilokopytov, Viktor Bohdanskyi ยท 2026

This note is a follow-up to \cite{bt}. We focus on conditions under which a normed lattice $X$ is majorizing in its norm completion. We show that \cite[Question 8.17]{bt} -- namely, whether this holdsโ€ฆ

Discovery of the Solution to the "Einstein-Podolsky-Rosen Paradox"

Roman Schnabel ยท 2026

In 1935, Albert Einstein, Boris Podolsky and Nathan Rosen (EPR) published a thought experiment that is entirely correct, has been demonstrated in real experiments, and is now the most famous in quantuโ€ฆ

The Josehedron: A space-filling plesiohedron based on the Fischer-Koch S Triply Periodic Minimal Surface

Mathias Bernhard ยท 2026

This paper presents a novel space-filling polyhedron (SFPH), here named the Josehedron, derived from the extremal points of the Fischer-Koch S triply periodic minimal surface (TPMS). The Josehedron isโ€ฆ

The Domb Ap'ery-limit and a proof of the Ramanujan Machine conjecture Z2

Alex Shvets ยท 2026

We prove that the ratio $B_n/D_n$ of the Ap\'ery-like sequence $B_n$ to the Domb numbers $D_n$ converges to $(7/24)\zeta(3)$, and that $\sum_{n=1}^{\infty} 64^n/(n^3 D_n D_{n-1}) = (56/3)\zeta(3)$. Asโ€ฆ

Sharp forms and quantitative stability for general weighted discrete $p$-Hardy inequalities

Nurgissa Yessirkegenov, Amir Zhangirbayev ยท 2026

In this paper, we provide a sharp remainder term for the general weighted discrete $p$-Hardy inequality. By simply choosing weights and specifying $1<p<\infty$, we are able to recover the identity by โ€ฆ

Fischer-Servi logic does not have interpolation

Rodrigo Nicolau Almeida, Nick Bezhanishvili, Simon Lemal ยท 2026

We prove that the Fischer-Servi logic $\mathsf{IK}$ does not have the (Craig) interpolation property. This is obtained by showing that the corresponding class of modal Heyting algebras lacks the amalgโ€ฆ

Simon's knot genus problem and Lewin $3$-manifold groups

Pablo Sanchez-Peralta ยท 2026

We provide a positive answer to an old problem of Jonathan K. Simon: if $K$ and $K'$ are two knots such that there is an epimorphism from the knot group of $K$ to the knot group of $K'$, then the genuโ€ฆ

Gamma-ray production in the cosmic-ray -- dark matter scattering as a probe of the axion-like particle -- proton interaction

Victor P. Goncalves, Emmanuel Moulin, Igor Reis, Aion Viana ยท 2026

The production of very-high-energy (VHE, $E_{\gamma} \gtrsim 100$ GeV) gamma rays resulting from the scattering of high-energy cosmic-ray protons off axion-like particles (ALPs) populating the dark maโ€ฆ

Tight (S)ETH-based Lower Bounds for Pseudopolynomial Algorithms for Bin Packing and Multi-Machine Scheduling

Karl Bringmann, Anita Durr, Karol Wegrzycki ยท 2026

Bin Packing with $k$ bins is a fundamental optimisation problem in which we are given a set of $n$ integers and a capacity $T$ and the goal is to partition the set into $k$ subsets, each of total sum โ€ฆ

Non-Lorentzian Supergravity from Matrix Theory

Dawid Maskalaniec, Ziqi Yan, Utku Zorba ยท 2026

It was recently shown that the decoupling limits leading to matrix (gauge) theories on D-branes give rise to non-Lorentzian target space geometries. Perturbatively, matrix theory describes a quantum gโ€ฆ

The Ghost in the Datacenter: Link Flapping, Topology Knowledge Failures, and the FITO Category Mistake

Paul Borrill ยท 2026

Every link disconnection or flap in a datacenter corrupts the network's self-knowledge -- its graph. We call this corruption a ghost: a node that appears reachable but is not, a link that reports "up"โ€ฆ
