Pseudo-Riemannian metrics on bicovariant bimodules

Published 14 Nov 2019 in math.QA, math-ph, and math.MP | (1911.06036v2)

Abstract: We study pseudo-Riemannian invariant metrics on bicovariant bimodules over Hopf algebras. We clarify some properties of such metrics and prove that pseudo-Riemannian invariant metrics on a bicovariant bimodule and its cocycle deformations are in one to one correspondence.
