WebChern-Weil construction generalizes to all such algebras. In this paper, we introduce a canonical Chern-Weil map Wg → A for possibly non-commutative g-diﬀerential algebras with connection. Our main observation is that the gener-alized Chern-Weil map is an algebra homomorphism “up to g-homotopy”. Hence, the induced map (Sg∗) inv → H
