Anosov vector fields and Fried sections

The purpose of this paper is to prove that if $Y$ is a compact manifold, if $Z$ is an Anosov vector field on $Y$, and if $F$ is a flat vector bundle, there is a corresponding canonical nonzero section ${\tau }_{\nu }\left(i_Z\right)$ of the determinant line $\nu =\det H(Y,F)$. In families, this section is $C^1$ with respect to the canonical smooth structure on $\nu$. When $F$ is flat on the total space of the corresponding fibration, our section is flat with respect to the Gauss-Manin connection on $\nu$.
