Cartan Connections and Atiyah Lie Algebroids
Jeremy Attard, Jordan François, Serge Lazzarini +1
This work extends previous developments carried out by some of the authors on Ehresmann connections on Atiyah Lie algebroids. In this paper, we study Cartan connections in a framew…
The dressing field method of gauge symmetry reduction, a review with examples
J. Attard, J. François, S. Lazzarini +1
Gauge symmetries are a cornerstone of modern physics but they come with technical difficulties when it comes to quantization, to accurately describe particles phenomenology or to e…
Tractors and Twistors from conformal Cartan geometry: a gauge theoretic approach II. Twistors
Jordan François, Jeremy Attard
Tractors and Twistors bundles both provide natural conformally covariant calculi on -Riemannian manifolds. They have different origins but are closely related, and usually cons…
Tractors and Twistors from conformal Cartan geometry: a gauge theoretic approach I. Tractors
Jeremy Attard, Jordan François
Tractors and Twistors bundles both provide natural conformally covariant calculi on -Riemannian manifolds. They have different origins but are closely related, and usually cons…
A Note on Weyl invariance in gravity and the Wess-Zumino functional
J. Attard, S. Lazzarini
It is shown that the explicit calculation of the Wess-Zumino functional pertaining to the breaking term of the Weyl symmetry for the Einstein-Hilbert action allows to restore the W…
Weyl gravity and Cartan geometry
Jeremy Attard, Jordan François, Serge Lazzarini
We point out that the Cartan geometry known as the second-order conformal structure provides a natural differential geometric framework underlying gauge theories of conformal gravi…
