This argument is similar to that of [12]. Let M be a smooth Riemannian manifold of dimension n with a Riemannian metric g. Let X1 , X2 , . . , Xn be a local orthonormal frame of T (M ) in a local path U . And let ω 1 , ω 2 , . . , ω n be its dual. The diﬀerential d and its dual ϑ acting on Γ(∧p T ∗ (M )) are written as follows,using the Levi-Civita connection ∇ (see Appendix A of [14]): n n ϑ=− e(ω j )∇Xj , d= j=1 ı(Xj )∇Xj , j=1 where we use the following notation. Notation. e(ω j )ω = ω j ∧ ω, ı(Xj )ω(Y1 , .

1. The Heisenberg group If we identify R2 with the complex plane C via R2 (x, y) ↔ z = x + iy ∈ C and let H = C × R, then H becomes a non-commutative group when equipped with the multiplication · given by 1 (z, t) · (w, s) = z + w, t + s + [z, w] , (z, t), (w, s) ∈ H, 4 where [z, w] is the symplectic form of z and w deﬁned by [z, w] = 2 Im(zw). In fact, H is a unimodular Lie group on which the Haar measure is just the ordinary Lebesgue measure dz dt.
