Einstein-Dirac theory on gauge-natural bundles
Paolo Matteucci
We present a clear-cut example of the importance of the functorial approach of gauge-natural bundles and the general theory of Lie derivatives for classical field theory, where the…
Metric-affine gravity and the Nester-Witten 2-form
Marco Godina, Paolo Matteucci, James A. Vickers
In this paper we redefine the well-known metric-affine Hilbert Lagrangian in terms of a spin-connection and a spin-tetrad. On applying the Poincaré-Cartan method and using the geom…
Two-spinor Formulation of First Order Gravity coupled to Dirac Fields
Marco Godina, Paolo Matteucci, Lorenzo Fatibene +1
Two-spinor formalism for Einstein Lagrangian is developed. The gravitational field is regarded as a composite object derived from soldering forms. Our formalism is geometrically an…
