Two-dimensional Id\`eles with Cycle Module Coefficients
, 2014 We give a theory of id\`eles with coefficients for smooth surfaces over a field. It is an analogue of Beilinson/Huber's theory of higher ad\`eles, but handling cycle module sheaves instead of quasi-coherent ones.

Characterization of global fields by Dirichlet L-series [PDF]
, 2019 We prove that two global fields are isomorphic if and only if there is an isomorphism of groups of Dirichlet characters that preserves L ...

Some remarks on K-lattices and the Adelic Heisenberg Group for CM curves
, 2015 We define an adelic version of a CM elliptic curve $E$ which is equipped with an action of the profinite completion of the endomorphism ring of $E$. The adelic elliptic curve so obtained is provided with a natural embedding into the adelic Heisenberg ...

La formule des traces tordue d'après le Friday Morning Seminar [PDF]
, 2013 International audienceThe trace formula for an arbitrary connected reductive group over a number field is due to James Arthur. The twisted case was the subject of the Friday Morning Seminar at the Institute for Advanced Study in Princeton during the ...

Poitou-Tate without restrictions on the order
, 2015 The Poitou-Tate sequence relates Galois cohomology with restricted ramification of a finite Galois module $M$ over a global field to that of the dual module under the assumption that $\#M$ is a unit away from the allowed ramification set.

Orbit-cone correspondence for the proalgebraic completion of normal toric varieties [PDF]
summary:We prove that there is an orbit-cone correspondence for the proalgebraic completion of normal toric varieties, which is analogous to the classical orbit-cone correspondence for toric ...

Cuntz-Li algebras from a-adic numbers [PDF]
, 2015 The a-adic numbers are those groups that arise as Hausdorff completions of noncyclic subgroups of the rational numbers. We give a crossed product construction of (stabilized) Cuntz-Li algebras coming from the a-adic numbers and investigate the structure ...

Riemann-Roch for the ring $\mathbb Z$
, 2023 We show that by working over the absolute base $\mathbb S$ (the categorical version of the sphere spectrum) instead of $\mathbb S[\pm 1]$ improves our previous Riemann-Roch formula for $\overline{{\rm Spec\,}\mathbb Z}$.

Hecke algebra isomorphisms and adelic points on algebraic groups [PDF]
, 2015 Let $G$ denote a linear algebraic group over $\mathbf{Q}$ and $K$ and $L$ two number fields. Assume that there is a group isomorphism of points on $G$ over the finite adeles of $K$ and $L$, respectively.

A note on small generators of number fields, II
, 2023 Let $K$ be an algebraic number field and $H$ the absolute Weil height. Write $c_K$ for a certain positive constant which is an invariant of $K$. We consider the question: does $K$ contain an algebraic integer $\alpha$ such that both $K = \mathbb{Q ...
