Towards Bigness equivalence

F. Laytimi, D. S. Nagaraj ยท 2026

On the flag variety $ \mathcal{F}l_s(E)$ associated to a vector bundle $E,$ , a sequence $s$ and a partition $a,$ there is a line bundle $\it Q^a_s$ on $ \mathcal{F}l_s(E).$ The aim of this papeโ€ฆ

A note on estimation of quarticity based on spot volatility

Yi Guo ยท 2026

In this paper, we aim at estimating the quarticity of continuous It\^{o} semimartingales. Instead of using some classical estimators, we introduce a more intuitive one and establish a central limit thโ€ฆ

Exotic Surfaces in 4-manifolds and Surface Corks

Cindy Zhang ยท 2026

A fundamental result in 4-manifold topology asserts that every exotic smooth structure on a simply connected closed 4-manifold is determined by a cork -- a codimension-zero compact, contractible submaโ€ฆ

Parameterization-driven arbitrary Lagrangian-Eulerian method for large-deformation isogeometric fluid-structure interaction

Jingya Li, Ye Ji, Hugo Verhelst, Henk den Besten, Matthias Moller ยท 2026

Body-fitted arbitrary Lagrangian-Eulerian (ALE) methods provide a sharp representation of the fluid-structure interface but rely on mesh-update strategies that incrementally deform a reference configuโ€ฆ

Pancyclicity in Graph Families with the Ore-Type Condition

Luyi Li, Yubo Wang, Guiying Yan ยท 2026

Let $ n \in \mathbb{N} $ with $ n \geq 3 $, and let $\mathcal{G} = \{G_i:i\in [n]\} $ be a family of $ n $-vertex graphs on a common vertex set $V$, where the graphs in the family do not need to be diโ€ฆ

Perfectoid splitting and global $+$-regularity for smooth hypersurfaces

Shou Yoshikawa ยท 2026

In this paper, we prove that smooth Calabi--Yau hypersurfaces of degree $d$ over complete unramified discrete valuation rings with residue characteristic $p$ are perfectoid split if $p$ is larger thanโ€ฆ

Exact Flatness Constant for One-Point Convex Bodies and the Discrete Isominwidth Problem: The Planar Case

Gennadiy Averkov, Giulia Codenotti, Ansgar Freyer, Kyle Huang ยท 2026

A variant of the flatness problem from integer programming is studied, in which one considers convex bodies in $\mathbb{R}^d$ with at most $k$ interior lattice points. The maximum lattice width of sucโ€ฆ

On the monotonicity of affine quermassintegrals

Shibing Chen, Yuanyuan Li, Xianduo Wang ยท 2026

Lutwak's affine quermassintegral theory is a foundational component of modern affine Brunn--Minkowski theory. Developed in the 1980s, it provides affine analogues of the classical quermassintegrals anโ€ฆ

Sharp One-Dimensional Sub-Gaussian Comparison in Convex Order

Yihan Zhang ยท 2026

We prove that any random variable $X$ whose moment generating function is point-wise upper bounded by that of $ G \sim \mathcal{N}(0,1) $ must be dominated by $ G/\mathbb{E}[|G|] $ in convex order, meโ€ฆ

When all parallel sets of a $ C^1 $-hypersurface are nowhere $ C^1 $-regular

Mario Santilli ยท 2026

We prove a necessary and sufficient condition for a $ C^1 $-hypersurface to have all parallel sets nowhere $ C^1 $-regular. As a corollary, we deduce that for a generic $ C^1 $-regular convex body allโ€ฆ

Approximating Periodic Orbits with Algebraic Curves and Related Minimal Problems

Ruiqi Huang, Anton Leykin ยท 2026

The Circular Restricted Three-Body Problem (CR3BP) models the motion of a massless body under the gravitational influence of two primaries. We present a method for approximating a given family of periโ€ฆ

The Expiring Coupon Collector: Sliding-Window Surjection Flux and Rare-Entry Laws

Christopher D. Long ยท 2026

We study the coupon collector with deterministic expiration: one coupon is drawn at each time, and each coupon remains active for exactly $M$ draws. Completion occurs when all $n$ coupon types are simโ€ฆ

A Schur-positivity classification for complete multipartite graphs

Ethan Shelburne, Stephanie van Willigenburg ยท 2026

A graph is Schur-positive if its chromatic symmetric function expands non-negatively in the Schur basis. We determine a full Schur-positivity classification for complete multipartite graphs by showingโ€ฆ

Dictionary learning for Kernel EDMD

Erik Lien Bolager, Boumediene Hamzi, Houman Owhadi, Ioannis G. Kevrekidis, Felix Dietrich ยท 2026

Studying nonlinear dynamical systems through their state space behavior can be challenging, and one possible alternative is to analyze them via their associated Koopman operator. This turns the nonlinโ€ฆ

Linear continuous operators with bounded supports

Vesko Valov ยท 2026

For any Tychonoff space $X$ let $D(X)$ be either the set $C(X)$ of all continuous functions on $X$ or the set $C^*(X)$ of all bounded continuous functions on $X$. When $D(X)$ is endowed with the pointโ€ฆ
