Arithmetic Wu Formulas and the Generalized Hecke Theorem

Shachar Carmeli, Mark Shusterman, Sa'ar Zehavi

We construct canonical stable Steenrod squares on modified compactly supported étale cohomology of separated finite-type schemes over rings of $S$ -integers in number fields with $2…

Modular Chabauty: Effective S-Integral Point Computation On Curves with Elliptic Fibrations

Sa'ar Zehavi

We present a practical, unconditional algorithm for determining the $S$ -integral points on any elliptic moduli problem $Y / Z [1/ S]$ -- that is, on any geometricall…

The Unipotent Chabauty-Kim-Kantor Method for Relative Completions

David Corwin, Sa'ar Zehavi

We develop a new $p$ -adic analytic method for studying integral points on hyperbolic curves, building on Kantor's relative-completion approach to unifying the Chabauty-Kim and Lawr…

Polylogarithmic motivic Chabauty-Kim for $P^{1} ∖ {0, 1, \infty}$ : the geometric step via resultants

David Jarossay, David T. -B. G. Lilienfeldt, Francesco Maria Saettone +2

Given a finite set $S$ of distinct primes, we propose a method to construct polylogarithmic motivic Chabauty-Kim functions for $P^{1} ∖ {0, 1, \infty}$ using resul…
