-invariant motivic cohomology of schemes

Tom Bachmann, Elden Elmanto, Matthew Morrow

Voevodsky outlined a conjectural programme that his slice filtration in motivic homotopy theory should give rise to a good theory of -invariant motivic cohomology. Th…

Motivic Steenrod operations at the characteristic via infinite ramification

Toni Annala, Elden Elmanto

We construct motivic power operations on the mod- motivic cohomology of $\Fb_p$-schemes using a motivic refinement of Nizioł's theorem. The key input is a purity theorem for mot…

On filtered algebraic -theory of stacks I: characteristic zero

Elden Elmanto, Dmitry Kubrak, Vladimir Sosnilo

Given a compact Lie group acting on a space , the classical Atiyah-Segal completion theorem identifies topological -theory of the homotopy quotient with an explicit…

Unstable motivic and real-étale homotopy theory

Aravind Asok, Tom Bachmann, Elden Elmanto +1

We prove that for any base scheme , real étale motivic (unstable) homotopy theory over coincides with unstable semialgebraic topology over (that is, sheaves of spaces on…

On the -theory of the -adic unit disk

Elden Elmanto, Noah Riggenbach

In this note, we study the -complete topological cyclic homology of the affine line relative to a ring which is smooth over a perfectoid ring . Denoting by $NTC(A; \mathb…

Proper splittings and projectivity for good moduli spaces

Dori Bejleri, Elden Elmanto, Matthew Satriano

We show that any good moduli space has a splitting after a proper, generically finite covering of . As an application we generalize Kollár's ampleness lem…
