Ab. Cruzeiro et Sz. Fang, Weak Levi-Civita connection for the damped metric on the Riemannian path space and vanishing of Ricci tensor in adapted differential geometry, J FUNCT ANA, 185(2), 2001, pp. 681-698
We shall establish in the context of adapted differential geometry on the p
ath space P-mo (M) a Weitzenbock formula which generalizes that in (A. B. C
ruzeiro and P. Malliavin, J. Funct. Anal. 177 (2000), 219-253), without hyp
othesis on the Ricci tenser. The renormalized Ricci tensor will be vanished
. The connection introduced in (A. B. Cruzeiro and S. Fang, 1997, J. Funct.
Anal, 143, 400 414) will play a central role. (C) 2001 Academic Press.
