Real Regulators on Self-Products of K3 Surfaces
Xi Chen, James D. Lewis
Based on a novel application of an archimedean type pairing to the geometry and deformation theory of surfaces, we construct a regulator indecomposable -class on a self-p…

Descent constructions for central extensions of infinite dimensional Lie algebras
Arturo Pianzola, Daniel Prelat, Jie Sun
We use Galois descent to construct central extensions of twisted forms of split simple Lie algebras over rings. These types of algebras arise naturally in the construction of Exten…

Resolving G-torsors by abelian base extensions
V. Chernousov, Ph. Gille, Z. Reichstein
Let G be a linear algebraic group defined over a field k. We prove that, under mild assumptions on k and G, there exists a finite k-subgroup S of G such that the natural map H^1(K,…
