Witt's theorem for noncommutative conics

Published 14 Mar 2015 in math.AG and math.QA | (1503.04341v3)

Abstract: Let k be a field. We show that all homogeneous noncommutative curves of genus zero over k are noncommutative P^1-bundles over a (possibly) noncommutative base. Using this result, we compute complete isomorphism invariants of homogeneous noncommutative curves of genus zero, allowing us to generalize a theorem of Witt.
