The Lie jet q l of a field of
geometric objects l on a smooth
manifold
with respect to a field q of Weil A-velocities is
a generalization of the Lie derivative v l of
a field l with respect to
a vector field .
In this paper, Lie jets q l are applied to the
study of A-smooth diffeomorphisms on a Weil bundle
AM of a smooth manifold , which are symmetries of
prolongations of geometric objects from to AM.
It is shown that vanishing of a Lie jet q
l is
a necessary and sufficient condition for the prolongation
lA
of a field of geometric
objects l to be invariant with
respect to the transformation of the Weil bundle AM induced by
the field q.
The case of symmetries of prolongations of fields of geometric objects
to the second-order tangent bundle 2M are
considered in more detail.
