Résumé

In this paper a Weil approach to quasijets is discussed. For given manifolds $M$ and $N$ , a quasijet with source $x \in M$ and target $y \in N$ is a mapping $T_{x}^{r} M \to T_{y}^{r} N$ which is a vector homomorphism for each one of the $r$ vector bundle structures of the iterated tangent bundle $T^{r}$ [A. Dekrét, Casopis Pest. Mat. 111, No. 4, 345-352 (1986; Zbl 0611.58004)]. Let us denote by $Q J^{r} (M, N)$ the bundle of quasijets from $M$ to $N$ ; the space ${\tilde{J}}^{r} (M, N)$ of non-holonomic $r$ -jets from $M$ to $N$ is embeded into $Q J^{r} (M, N)$ . On the other hand, the bundle $Q T_{m}^{r} N$ of $(m, r)$ -quasivelocities of $N$ is defined to be $Q J_{0}^{r} (𝐑^{m}, N)$ ; then, $Q T_{m}^{r}$ is a product preserving functor and so a Weil functor $T^{𝐐_{m}^{r}}$ where $𝐐_{m}^{r}$ is the Weil algebra $Q T_{m}^{r} 𝐑$ [see I. Kolár, P. Michor and J. Slovák, ‘Natural operations in differential geometry’ (Springer-Verlag, Berlin) (1993; Zbl 0782.53013)]; next, t!
