The $H$-linkage problems in sparse robustly expanding digraphs

Zhilan Wang, Jin Yan · 2026

The Nash-Williams conjecture establishes degree sequence conditions ensuring Hamilton cycles in digraphs. An asymptotic version of this conjecture for large digraphs was independently derived by sever…

Semistable reductions and minimalities of invariants for group scheme actions on projective schemes

Rin Gotou, Yusuke Okuyama · 2026

Let $K$ be an algebraically closed and complete non-archimedean and non-trivially valued field, and let $G$ be a reductive group scheme acting on a flat projective scheme $X$ defined over the base rin…

Volitional Multiagent Atomic Transactions: Describing People and their Machines

Andy Lewis-Pye, Ehud Shapiro · 2026

Formal models for concurrent and distributed systems describe machines; the people who operate them are either ignored or treated as external environment. Yet key distributed systems -- notably grassr…

Triangle packings in randomly perturbed graphs

Xinbu Cheng, Hong Liu, Lanchao Wang, Zhifei Yan · 2026

The longstanding Nash-Williams conjecture asserts that every $K_3$-divisible graph $G$ with $\delta(G)\ge 3n/4$ admits a triangle decomposition. In the random setting, Frankl and R\"odl showed that, w…

Constructive Separations from Gate Elimination

Marco Carmosino, Ngu Dang, Tim Jackman · 2026

Gate elimination is the primary technique for proving explicit lower bounds against general Boolean circuits, including Li and Yang's state-of-the-art $3.1n - o(n)$ bound for affine dispersers (STOC 2…

Unconstrained and Ropelength-Windowed $p$-densities of Knot Types

Makoto Ozawa · 2026

We study a family of scale-invariant $p$-densities of knot types in $R^3$, defined as the ratio of length to an $L^p$-type spread of pairwise distances along a curve. The first point of the paper is t…

Hybrid Conjecture in a Mixed Shimura variety

Rodolphe Richard, Andrei Yafaev · 2026

The authors previously formulated the hybrid conjecture, unifying Andr\'e-Pink-Zannier and Andr\'e-Oort conjectures, and proved it in Shimura varieties of abelian type. We study its analogue for mixed…

Matched asymptotics of Rayleigh-wave fields near cuspidal ridges and gorges

Oleg Kiselev · 2026

We construct a local matched-asymptotic description of time-harmonic elastic fields generated by Rayleigh waves near cuspidal elements of a traction-free surface. The free surface is represented local…

p-adic elliptic polylogarithms and cubic Chabauty

Jennifer S. Balakrishnan, Francesca Bianchi, Netan Dogra · 2026

The Chabauty--Coleman--Kim method, under favourable circumstances, describes the set of integral points of a hyperelliptic curve inside the $p$-adic zeroes of certain transcendental functions. For an …

On Uniqueness of Mock Theta Functions

Ovidiu Costin, Gerald V. Dunne, Ali Saraeb · 2026

We develop a resurgent approach to the problem of unique continuation of mock theta functions across their natural boundary. The starting point is the representation of the associated Mordell-Appell i…

A Rademacher exact type formula for pod$_2(n)$

Kilian Rausch · 2026

In this paper, we calculate an exact formula for the number of partitions of a natural number $n$, where the largest part is even and no odd parts appears more than two times. The generating functions…

What if we have 90 minutes only to teach programming?

Attila Egri-Nagy · 2026

Programming is about automation in a wide variety of domains. Developing itself is one of those. As a side-effect, progress in automated coding may make people less willing to learn computer programmi…
