Compatibility of -isocrystals on adjoint Shimura varieties

Jake Huryn, Kiran S. Kedlaya, Christian Klevdal +1

In this article, we extend past results of the last two authors to include compatibility of canonical -adic local systems and canonical -isocrystals on adjoint Shimura var…

Etale and crystalline companions, II

Kiran S. Kedlaya

Let be a smooth scheme over a finite field of characteristic . In answer to a conjecture of Deligne, we establish that for any prime , an -adic Weil sheaf…

On the relative Nullstellensatz in nonarchimedean geometry

Kiran S. Kedlaya, Yutaro Mikami

We establish a relative version of the Nullstellensatz for algebras topologically of finite type over a given Banach Tate ring , under the assumption that the corresponding stat…

The exceptional set in Cassel's theorem on small cyclotomic integers

Jitendra Bajpai, Srijan Das, Kiran S. Kedlaya +4

In a 1965 paper, R. Robinson made five conjectures about the classification of cyclotomic algebraic integers for which the maximum absolute value in any complex embedding (the hous…

Monodromy representations of -adic differential equations in families

Kiran S. Kedlaya

We derive a relative version of the local monodromy theorem for ordinary differential equations on an annulus over a mixed-characteristic nonarchimedean field, and give several app…

Bounds for the relative class number problem for function fields

Santiago Arango-Piñeros, María Chara, Asimina S. Hamakiotes +2

We establish bounds on a finite separable extension of function fields in terms of the relative class number, thus reducing the problem of classifying extensions with a fixed relat…
