Towards the Chern-Weil homomormism in non-commutative differential geometry
Abstract
In this short review article we sketch some developments which should ultimately lead to the analogy of the Chern-Weil homomorphism for principal bundles in the realm of non-commutative differential geometry. Principal bundles there should have Hopf algebras as structure `cogroups'. Since the usual machinery of Lie algebras, connection forms, etc\., just is not available in this setting, we base our approach on the Fr\"olicher--Nijenhuis bracket.
