Abstract.
Let \(FM,{\cal M}_M\) be the bundles of linear frames and Riemannian metrics of a manifold M, respectively. The existence of a unique Diff M-invariant connection form on \(J^1{\cal M}_M\times _M FM\rightarrow J^1{\cal M}_M\), which is Riemannian with respect to the universal metric on \(J^1{\cal M}_M\times _M TM\), is proved. Applications to the construction of universal Pontryagin and Euler forms, are given.
