Parameterization of factorizable line bundles by K-theory and motivic cohomology

Algebraic Geometry 2020-05-12 v4

Abstract

This note corrects a certain construction in (the old version of) the paper [GL]. The construction in question starts from a Brylinski-Deligne datum, which is an extension of a group G by K_2, and produces a factorization line bundle on the affine Grassmannian of the group G.
