Étale motives of geometric origin

Bulletin of the London Mathematical Society, Volume 57, Issue 7, Page 2116-2131, July 2025.
Abstract Over qcqs finite‐dimensional schemes, we prove that étale motives of geometric origin can be characterised by a constructibility property which is purely categorical, giving a full answer to the question ‘Do all constructible étale motives come from geometry?’ which dates back to Cisinski and Déglise's work.

Hilbert–Kunz multiplicity of powers of ideals in dimension two

Bulletin of the London Mathematical Society, Volume 57, Issue 7, Page 2155-2176, July 2025.
Abstract We study the behavior of the Hilbert–Kunz multiplicity of powers of an ideal in a local ring. In dimension 2, we provide answers to some problems raised by Smirnov, and give a criterion to answer one of his questions in terms of a “Ratliff–Rush version” of the Hilbert–Kunz multiplicity.

Preservation for generation along the structure morphism of coherent algebras over a scheme

Bulletin of the London Mathematical Society, Volume 57, Issue 6, Page 1885-1896, June 2025.
Abstract This work demonstrates classical generation is preserved by the derived pushforward along the structure morphism of a noncommutative coherent algebra to its underlying scheme. Additionally, we establish that the Krull dimension of a variety over a field is a lower bound for the Rouquier dimension of the bounded derived category associated with

The structure of the classifying ring of formal groups with complex multiplication

, 2015
If $A$ is a commutative ring, there exists a classifying ring $L^A$ of formal groups with complex multiplication by $A$, i.e., "formal $A$-modules." In this paper, the basic properties of the functor that sends $A$ to $L^A$ are developed and studied ...

Localization of injective modules over valuation rings

, 2005
It is proved that the localization of an injective module E, over a valuation ring R, at a prime ideal J, is injective if J is not the subset of zero-divisors of R or if J or E is flat. It follows that localizations of injective modules over h-local Pr\"{
