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

Roman Schnabel · 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 quantu…

Boxer: Robust Lifting of Open-World 2D Bounding Boxes to 3D

Daniel DeTone, Tianwei Shen, Fan Zhang, Lingni Ma, Julian Straub, Richard Newcombe, Jakob Engel · 2026

Detecting and localizing objects in space is a fundamental computer vision problem. While much progress has been made to solve 2D object detection, 3D object localization is much less explored and far…

A note on piercing discrete rectangles

Wei Rao · 2026

In 2008, Halman proved a discrete Helly-type theorem for axis-parallel boxes in $\mathbb R^d$. Very recently, this result was extended to the $(p,q)$ setting with $p \geq q \geq d+1$ by Edwards and So…

Point-free MV-topologies

Marby Zuley Bolanos Ortiz, Luz Victoria De La Pava, Ciro Russo · 2026

We propose a point-free approach to MV-topological spaces in the wake of previous works on both classical and fuzzy topology. In order to do that, we introduce suitable frame-type structures and a cla…

From Calabi's extremal metrics to scalar-flat K\"ahler cones

Vestislav Apostolov, Abdellah Lahdili, Chung-Ming Pan · 2026

We prove that for any smooth polarized complex $n$-dimensional manifold $(X, L_X)$ which admits an extremal K\"ahler metric in $c_1(L_X)$, and for any integer $k$ large enough (in terms of a bound dep…

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

Pablo Sanchez-Peralta · 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 genu…

Kaon Boer-Mulders function using a contact interaction

Dan-Dan Cheng, Minghui Ding, Daniele Binosi, Craig D. Roberts · 2026

Using a symmetry preserving treatment of a vector*vector contact interaction (SCI), results are delivered for the four kaon transverse momentum dependent parton distribution functions (TMDs), viz. hel…

Unified description of Sivers and Boer-Mulders asymmetries from twist-3 correlations

Zhimin Zhu, Jiangshan Lan, Chandan Mondal, Xingbo Zhao, James P. Vary, BLFQ Collaboration · 2026

We present the first calculation of the Efremov-Teryaev-Qiu-Sterman functions and associated twist-3 quark-gluon correlation functions for both the proton and pion. These functions are determined usin…

Analytic Study of $p$-Bessel Functions: Fractional Calculus, Integral Representations, and Complex Extensions

Masaya Kitajima · 2026

We present a systematic analytic study of the $p$-Bessel functions $\mathcal{J}_{\omega,\varphi}^{[p]}$, a novel class of generalized Bessel functions arising from Fourier analysis on planar domains b…

The Extended Real Line with Reentry: Separating US from KC in the Clontz Hierarchy

Damian Rafael Lattenero · 2026

We construct the Extended Real Line with Reentry (ERI): identify $\{-\infty, 0, +\infty\}$ to a single point $\ast$ in $\overline{\mathbb{R}}$, and require every neighborhood of $\ast$ to have dense p…

Tensegrity Robot Endcap-Ground Contact Estimation with Symmetry-aware Heterogeneous Graph Neural Network

Wenzhe Tong, Yicheng Jiang, Chi Zhang, Maani Ghaffari, Xiaonan Huang · 2026

Tensegrity robots possess lightweight and resilient structures but present significant challenges for state estimation due to compliant and distributed ground contacts. This paper introduces a symmetr…

Weakening the Legendre Conjecture

Marc Chamberland, Armin Straub · 2026

The world of primes has many gaps between evidence and theorems. Here, we review Legendre's conjecture on primes between consecutive squares and recent progress on the weaker question of primes betwee…

Bredon cohomology methods in mass partition problems on spheres

Surojit Ghosh · 2026

We apply $\mathrm{RO}(G)$-graded Bredon cohomology to mass assignment problems, extending classical mass partition methods. Within this framework, we reprove a recent result of Lessure and Sober\'on: …

Quadratic irrational analogues of Ramanujan's series for $1/\pi$

John M. Campbell, Shaun Cooper, Dongxi Ye · 2026

About 40 years ago Jonathan and Peter Borwein discovered the series identity $$ \sum_{n=0}^\infty \frac{(-1)^n(6n)!}{(3n)!(n!)^3} \frac{(A+nB)}{C^{n+1/2}} = \frac{1}{12\pi} $$ where \begin{align*} A&=…
