On the structure of prime-detecting quasimodular forms in higher levels

Yeong-Wook Kwon, Youngmin Lee ยท 2026

Craig, van Ittersum, and Ono conjectured that every prime-detecting quasimodular form of level $1$ is a quasimodular Eisenstein series. This conjecture was proved by Kane--Krishnamoorthy--Lau and by vโ€ฆ

Constructing Parabolic Non-Abelian Hodge Correspondence in Positive Characteristic Using Parabolic Bases

Xiaojin Lin ยท 2025

We introduce the concept of parabolic bases to establish a localized framework for parabolic bundles and parabolic $\lambda$-connections. Building on this foundation, we propose a novel method for conโ€ฆ

Trace reconstruction of matrices and hypermatrices

Wenjie Zhong, Xiande Zhang ยท 2024

A \emph{trace} of a sequence is generated by deleting each bit of the sequence independently with a fixed probability. The well-studied \emph{trace reconstruction} problem asks how many traces are reqโ€ฆ

Constructing abelian varieties from rank 3 Galois representations with real trace field

Raju Krishnamoorthy, Yeuk Hay Joshua Lam ยท 2024

Let $U/K$ be a smooth affine curve over a number field and let $L$ be an irreducible rank 3 $\overline{\mathbb Q}_{\ell}$-local system on $U$ with trivial determinant and infinite geometric monodromy โ€ฆ

Efficient numerical methods for the Maxey-Riley-Gatignol equations with Basset history term

Julio Urizarna-Carasa, Leon Schlegel, Daniel Ruprecht ยท 2024

The Maxey-Riley-Gatignol equations (MRGE) describe the motion of a finite-sized, spherical particle in a fluid. Because of wake effects, the force acting on a particle depends on its past trajectory. โ€ฆ

Rotating Rayleigh-Benard convection: Attractors, bifurcations and heat transport via a Galerkin hierarchy

Roland Welter ยท 2024

Motivated by the need for energetically consistent climate models, the Boussinessq-Coriolis (BC) equations are studied with a focus on the averaged vertical heat transport, ie the Nusselt number. A seโ€ฆ

A tight linear chromatic bound for ($P_3\cup P_2, W_4$)-free graphs

Rui Li, Jinfeng Li, Di Wu ยท 2023

For two vertex disjoint graphs $H$ and $F$, we use $H\cup F$ to denote the graph with vertex set $V(H)\cup V(F)$ and edge set $E(H)\cup E(F)$, and use $H+F$ to denote the graph with vertex set $V(H)\cโ€ฆ

Some improved Gaussian correlation inequalities for symmetrical n-rectangles extended to some multivariate gamma distributions and some further probability inequalities

Thomas Royen ยท 2020

The Gaussian correlation inequality (GCI) for symmetrical n-rectangles is improved if the absolute components have a joint cumulative distribution (cdf) which is MTP2 (multivariate totally positive ofโ€ฆ
