Cartier crystals and dual-constructible -torsion complexes
Jefferson Baudin, Kay Rülling
We show that given a Noetherian and -finite scheme, the fixed point functor on Cartier crystals is fully faithful to the category of sheaves on the flat and relatively perfect s…
Lectures on the cohomology of reciprocity sheaves
Nikolai Opdan, Kay Rülling
These are the notes accompanying three lectures given by the second author at the Motivic Geometry program at CAS, which aim to give an introduction and an overview of some recent…
Ramification theory of reciprocity sheaves, II, Higher local symbols
Kay Rülling, Shuji Saito
We construct a theory of higher local symbols along Parsin chains for reciprocity sheaves. Applying this formalism to differential forms, gives a new construction of the Parsin-Lom…
Ramification theory of reciprocity sheaves, I, Zariski-Nagata purity
Kay Rülling, Shuji Saito
We prove a Zariski-Nagata purity theorem for the motivic ramification filtration of a reciprocity sheaf. An important tool in the proof is a generalization of the Kato-Saito recipr…
Cycle class maps for Chow groups of zero-cycles with modulus
Kay Rülling, Shuji Saito
For a quasi-projective smooth scheme X of pure dimension d over a field k and an effective Cartier divisor D on X whose support is a simple normal crossing divisor, we construct a…
Loops on schemes and the algebraic fundamental group
Kay Rülling, Stefan Schröer
In this note we give a re-interpretation of the algebraic fundamental group for proper schemes that is rather close to the original definition of the fundamental group for topologi…
