ABSTRACT: The goal of this paper is to introduce some applications and consequences of the injectivity of the map $\f(R) \ra \f(K)$ induced by the canonical inclusion of a local regular ring $R$ of geometric type to its field of fractions $R \hra{} K$, where $\f$ is a homotopy invariant functor with transfers. In particular, we get an original proof of a Grothendieck Conjecture about principal homogeneous spaces for Special Unitary group.
