Abstract

Given a compact Lie group G endowed with, its left invariant Cartan connection, we consider the path space P over G and its Wiener measure P. It is known that there exists a differentiable measurable isomorphism I between the classical Wiener space (W, μ) and (P, P). See [A], [D], [S2], [PU], [G].

In this article, using the pull-back by I we establish the De Rham-Hodge-Kodaira decomposition theorem on (Λ(P)P).
