Dimensional reduction of AdS3 Chern-Simons gravity: Schwarzian and affine boundary theories
Goffredo Chirco, Lucio Vacchiano, Patrizia Vitale
We study a symmetry-reduced sector of gravity formulated as an Chern--Simons theory on a three-dimensional manifold with toroidal boundary. The reduction is imple…

The electromagnetic field in Poisson gauge theory: the groupoidal approach
Fabio Di Cosmo, Vladislav G. Kupriyanov, Patrizia Vitale
We consider the problem of defining the field strength of abelian potentials when the spacetime is a Poisson manifold, within the groupoidal approach. The natural definition in ter…

Jacobi Sigma Models and Twisted Jacobi Structures
Francesco Bascone, Franco Pezzella, Patrizia Vitale
Jacobi sigma models are two-dimensional topological non-linear field theories which are associated with Jacobi structures. The latter can be considered as a generalization of Poiss…
