Higher order transverse bundles and riemannian foliations    [PDF]

Paul Popescu

The purpose of this paper is to prove that each of the following conditions is equivalent to that the foliation ${\cal F}$ is riemannian: 1) the lifted foliation ${\cal F}^{r}$ on the $r$-transverse bundle $\nu ^{r}{\cal F}$ is riemannian for an $r\geq 1$; 2) the foliation ${\cal F}_{0}^{r}$ on a slashed $\nu_{\ast}^{r}{\cal F}$ is riemannian and vertically exact for an $r\geq 1$; 3) there is a positively admissible transverse lagrangian on a $% \nu_{\ast}^{r}{\cal F}$, for an $r\geq 1$. Analogous results have been proved previously for a transverse jet bundle.
