Dynamical dark energy and gravitational coupling from moving geometries
Jean Thibaut
We introduce the notion of moving Cartan geometries described by quotients of Lie groups and Lie algebras with spacetime dependant structure constants and construct associated defo…

Gravity as a deformed topological gauge theory
J. Thibaut, S. Lazzarini
We describe gauge theories which allow to retrieve a large class of gravitational theories, including, MacDowell-Mansouri gravity and its topological extension to Loop Quantum Grav…
