Let M be a C -manifold with a Riemannian conformal structure C . Given a regular curve γ on M , the authors define a linear operator on the space of (differentiable) vector fields along γ , only depending on C , called the Fermi-Walker connection along γ . Then, the authors introduce the concept of Fermi-Walker parallel vector field along γ , proving that such vector fields set up a linear space isomorphic to the tangent space at a point of γ . This allows to consider the Fermi-Walker horizontal lift of γ to the bundle C O ( M ) of conformal frames on M and to define, for any conformal frame b at a point p , a lift function k b from the set of 2-jets of regular curves on M starting at p into the tangent space T b ( C O ( M ) ) . Finally, using the lift functions k b , b C O ( M ) , the authors construct a trivialization of the fiber bundle C O ( M ) 1 over C O ( M ) , C O ( M ) 1 , denoting the first prolongation of !
