On the generalized Bass--Quillen conjecture in dimension 2

Anastasia Stavrova

Let be a regular ring of dimension . Let be a reductive group over such that its derived group is a split, i.e. a Chevalley--Demazure, semisimple group. We prove…

Non-Stable -Functors of Discrete Valuation Rings Containing a Field

Philippe Gille, Anastasia Stavrova

Let be a field, and let be a simply connected semisimple k-group which is isotropic and contains a strictly proper parabolic -subgroup . Let be a discrete valuati…

On a theorem of Harder

Ivan Panin, Anastasia Stavrova

We prove that for any simply connected isotropic reductive group G over a Dedekind domain D, any Zariski-locally trivial principal G-bundle over D is trivial. The corresponding res…

Chevalley groups over Laurent polynomial rings

Anastasia Stavrova

Let be a simply connected Chevalley--Demazure group scheme without -factors. For any unital commutative ring , we denote by the standard elementary subgroup of…

On the Gille theorem for the relative projective line

Ivan Panin, Anastasia Stavrova

Let be a Noetherian separated scheme. Let be a reductive -group scheme, and let be a principal -bundle over . We prove that if the restriction of…

On the Gille theorem for the relative projective line: I

Ivan Panin, Anastasia Stavrova

We prove a relative version of a theorem on torsors on the projective line due to Philippe Gille. As a consequence we obtain a ``weak homotopy invariance'' result for torsors under…
