Gravity, spinors and gauge-natural bundles
… 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 gravity and spinor fields. In Chapter 1 we recall the necessary background material from differential geometry …

Jet groupoids, natural bundles and the Vessiot equivalence method
… geometric objects, the central concept of natural bundles is introduced. They are used to test equivalence of different geometric objects. For this, the symmetries of the objects and invariants are necessary. Lie and Vessiot showed that coordinate transfomations of natural bundles can be …
