The third homology of SL_2 of local rings (1309.5010v2)
Published 19 Sep 2013 in math.KT
Abstract: We describe the third homology of SL_2 of local rings over Z[1/2] in terms of a refined Bloch group. We use this to derive a localization sequence for the third homology of SL_2 of certain discrete valuation rings, and to make explicit computations for p-adic integers and other local rings.
