Covariant connections on bicovariant differential calculus
Jyotishman Bhowmick, Sugato Mukhopadhyay
Given a bicovariant differential calculus such that the braiding map is diagonalisable in a certain sense, the bimodule of two-tensors admits a direct sum decomp…

Pseudo-Riemannian metrics on bicovariant bimodules
Jyotishman Bhowmick, Sugato Mukhopadhyay
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 metr…
