Central extensions by K2 and factorization line bundles
Let X be a smooth, geometrically connected curve over a perfect field k. Given a connected, reductive group G, we prove that central extensions of G by the sheaf K2 on the big Zariski site of X, studied in Brylinski-Deligne [5], are equivalent to factorization line bundles on the Beilinson-Drinfeld...
