Abstract Reductive G -structures on a principal bundle Q are considered. It is shown that these structures, i.e. reductive G -subbundles P of Q , admit a canonical decomposition of the pull-back vector bundle i P ∗ (TQ)≡P× Q TQ over P . For classical G -structures, i.e. reductive G -subbundles of the linear frame bundle, such a decomposition defines an infinitesimal canonical lift. This lift extends to a prolongation Γ -structure on P . In this general geometric framework the theory of Lie… Expand

Gravity, spinors and gauge-natural bundles
The purpose of this thesis is to give a fully gauge-natural formulation of gravitation theory, which turns out to be essential for a correct geometrical formulation of the coupling between gravityExpand
Gauge-natural field theories and Noether Theorems: canonical covariant conserved currents
AbstractRecently we found that canonical gauge-natural superpotentials areobtained as global sections of the reduced (n−2)-degree and (2s−1)-orderquotient sheaf on the fibered manifold Y ζ × X K,Expand
Axiomatic classical (prequantum) field theory. Jet formalism
In contrast with QFT, classical field theory can be formulated in a strict mathematical way if one defines even classical fields as sections of smooth fiber bundles. Formalism of jet manifoldsExpand

The issue of general covariance of spinors and related objects is reconsidered. Given an oriented manifold M, to each spin structure ? and Riemannian metric g there is associated a space S?, g ofExpand
Do Barbero-Immirzi connections exist in different dimensions and signatures?
We shall show that no reductive splitting of the spin group exists in dimension 3 \leq m \leq 20 other than in dimension m = 4. In dimension 4 there are reductive splittings in any signature.Expand


Split structures in general relativity and the Kaluza–Klein theories
We construct a general approach to the decomposition of the tangent bundle of pseudo-Riemannian manifolds into direct sums of subbundles, and the associated decomposition of geometric objects. AnExpand

A geometric definition of Lie derivative for Spinor Fields
Relying on the general theory of Lie derivatives a new geometric definition of Lie derivative for general spinor fields is given, more general than Kosmann's one. It is shown that for particularExpand
