Hamiltonian formulation of a gravity model from (A)dS Yang-Mills theory
Goffredo Chirco, Alfonso Lamberti, Patrizia Vitale
We study the Hamiltonian formulation of a gravity model obtained from a Yang--Mills theory for a one-parameter family of (A)dS Lie algebras parametrized by , when the family of…

Gravity model from (A)dS Yang-Mills theory
Goffredo Chirco, Alfonso Lamberti, Lucio Vacchiano +1
We investigate the relationship between a one-parameter family of (anti-)de Sitter Yang-Mills models and a model of Einstein-Palatini gravity with matter, realized through Inönu-W…

A so(2,2) extension of JT gravity via the Virasoro-Kac-Moody semidirect product
Goffredo Chirco, Lucio Vacchiano, Patrizia Vitale
We consider a bulk plus boundary extension of Jackiw-Teitelboim Gravity (JT) coupled with non-abelian gauge fields. The generalization is performed in the Poisson Sigma Model formu…
