Subgroups of Finite Fields As Cap Sets

Anthony Kable, Melissa Mills, David J. Wright ยท 2026

We show the subgroup of 20 nonzero fourth powers in the finite field of order 81 is a cap set. Similarly, the subgroup of 9 nonzero seventh powers in the field of order 64 is a cap set. These are the โ€ฆ

On D-cap-Modules of Finite Length on Rigid Analytic Spaces

Julian Reichardt ยท 2026

We show that for quasi-compact smooth rigid analytic spaces, the extension functor sends holonomic D-modules to coadmissible D-cap-modules which are of finite length as weakly holonomic D-cap-modules.โ€ฆ

Spherical Cap $L_2$ Discrepancy -- Blessing of Dimensionality and a Balanced Large-Cap Variant

Johann S. Brauchart, Josef Dick, Friedrich Pillichshammer ยท 2026

We prove that the information complexity (i.e., the inverse) of the classical spherical cap $L_2$ discrepancy on the $d$-dimensional sphere $\mathbb{S}^d$ decreases with dimension $d$, indicating a ``โ€ฆ

A note on small cap square function and decoupling estimates for the parabola

Jongchon Kim, Liang Wang, Chun Keung Yeung ยท 2026

In this paper, we prove small cap square function and decoupling estimates for the parabola, where the small caps are essentially axis-parallel rectangles of dimensions $\delta\times \delta^\beta$ forโ€ฆ

On the choice of viscous discontinuous Galerkin discretization for entropy correction artificial viscosity methods

Samuel Q. Van Fleet, Jesse Chan ยท 2026

Entropy correction artificial viscosity (ECAV) is an approach for enforcing a semi-discrete entropy inequality through an entropy dissipative correction term. The resulting method can be implemented aโ€ฆ

Global well-posedness for one-dimensional compressible Navier--Stokes system in dynamic combustion with small $BV\cap L^1$ initial data

Siran Li, Haitao Wang, Jianing Yang ยท 2026

We establish the global well-posedness theory of small BV weak solutions to a one-dimensional compressible Navier--Stokes model for reacting gas mixtures in dynamic combustion. The unknowns of the PDEโ€ฆ

New Method for Constructing Complete Cap Sets

Iskandar Karapetyana, Karen Karapetyana ยท 2026

A cap set in projective or affine geometry over a finite field is a set of points no three of which are collinear. In this paper, we propose a new construction for complete cap sets that yields a cap โ€ฆ

Holonomic D-cap-modules on rigid analytic spaces

Andreas Bode ยท 2025

We adapt Caro's notion of overholonomicity to give a definition of holonomic D-cap-modules on rigid analytic spaces. We prove stability under five of the six operations (both inverse image functors, dโ€ฆ

Extended Contact Algebras: Algebraic analysis and duality theory

Rafa{l} Gruszczynski, Paula Menchon, William Zuluaga ยท 2025

The ternary extended contact relation was introduced in (Ivanova, 2020) as a more expressive counterpart of the standard binary contact relation. The class of Boolean algebras expanded with the relatiโ€ฆ

Provability interpretation of non-normal modal logics having neighborhood semantics

Haruka Kogure ยท 2025

We study provability predicates $\mathrm{Pr}_T(x)$ satisfying the following condition $\mathbf{E}$ from a modal logical perspective: $\mathbf{E}:$ if $ T \vdash \varphi \leftrightarrow \psi$, then $T โ€ฆ

D-cap modules are quasi-coherent sheaves on an analytic stack

Arun Soor ยท 2025

We construct a fully-faithful functor of $\infty$-categories from complexes of D-cap modules with Fr\'echet cohomology to quasi-coherent sheaves on an analytic stack. We prove various descent results โ€ฆ

Hadwiger's conjecture for cap bodies

Andrii Arman, Jaskaran Singh Kaire, Andriy Prymak ยท 2025

Hadwiger's covering conjecture is that every $n$-dimensional convex body can be covered by at most $2^n$ of its smaller positive homothetic copies, with $2^n$ copies required only for affine images ofโ€ฆ
