On transformation groups of $$N$$-linear connections in the bundle of accelerations. (English) Zbl 0972.53019
The author proves that the set $$\mathcal T$$ of the transformations of $$N$$-linear connections on the bundle of accelerations $$\text{Osc}^2M$$ is a group. Several special subgroups and some expressions as semidirect products of $$\mathcal T$$ are emphasized.
