Linearization of nonlinear connections on vector and affine bundles, and some applications
A linear connection is associated to a nonlinear connection on a vector
bundle by a linearization procedure. Our definition is intrinsic in terms of
vector fields on the bundle. For a connection on an affine bundle our procedure
can be applied after homogenization and restriction. Several applications in
Classical Mechanics are provided

On special types of nonholonomic -jets
summary:We deduce a classification of all special types of nonholonomic -jets. In the introductory part, we summarize the basic properties of nonholonomic -jets
Prolongation of pairs of connections into connections on vertical bundles
summary:Let be a natural bundle. We introduce the geometrical construction transforming two general connections into a general connection on the -vertical bundle. Then we determine all natural operators of this type and we generalize the result by IK̇olář and the second author on the prolongation of connections to -vertical bundles. We also present some examples and applications
Contact elements on fibered manifolds
summary:For every product preserving bundle functor on fibered manifolds, we describe the underlying functor of any order . We define the bundle of -dimensional contact elements of the order on a fibered manifold and we characterize its elements geometrically. Then we study the bundle of general contact elements of type . We also determine all natural transformations of into itself and of into itself and we find all natural operators lifting projectable vector fields and horizontal one-forms from to
