Distributions on manifolds are studied in terms of jets of submanifolds and are interpreted as «pre-connections» or «almost-fibrings»; the associated differential calculus is developed in detail. A comparison with connections on fibred manifolds is analysed. Moreover, «higher order pre-connections», defined as pre-connections dependent on jets of arbitrary order, are introduced and studied. It is shown that infinite jets play an essential role in the associated differential calculus. 

Some cohomological aspects of the calculus of variations on finite-order jets of submanifolds

We show that on finite-order jets of submanifolds there exists a sequence, the finite-order variational sequence, which allows to formulate the calculus of variations in a purely

On the geometry of Grassmannian equivalent connections

We introduce the equation of n-dimensional totally geodesic submanifolds of a manifold E as a submanifold of the second order jet space of n-dimensional submanifolds of E. Next we study the geometry

The geometry of geodesic equation in the framework of jets of submanifolds

The geometry of differential equations and their higher symmetries is studied by using spaces of jets of submanifolds. The geodesic equation g introduced in this framework is proved to be a third

The geometry of finite order jets of submanifolds and the variational formalism

We study the geometry of jets of submanifolds with special interest in the relationship with the calculus of variations. We give a new proof of the fact that higher order jets of submanifolds are

Lagrangian and Hamiltonian dynamics of submanifolds

Submanifolds of a manifold are described as sections of a certain fiber bundle that enables one to consider their Lagrangian and (polysymplectic) Hamiltonian dynamics as that of a particular

Variational sequences on finite order jets of submanifolds

The theory of finite order variational sequences has been recently developed trough Krupka’s finite order variational bicomplex and Vinogradov’s C-spectral sequence. Such theories are formulated on

A linear connection on a differentiable manifold M defines a horizontal distribution on the tangent bundle T(M). Horizontal distributions on tangent bundles are of some interest even when they are

Local symmetries and conservation laws

Starting with Lie's classical theory, we carefully explain the basic notions of the higher symmetries theory for arbitrary systems of partial differential equations as well as the necessary
