Note About Non-Relativistic Diffeomorphism Invariant Gravity Action in Three Dimensions
arXiv:1401.7812 · doi:10.1103/PhysRevD.89.104036
Abstract
This short note is devoted to the Hamiltonian analysis of three dimensional gravity action that was proposed recently in [arXiv:1309.7231]. We modify given action in order to be invariant under non-relativistic diffeomorphism. Then we perform Hamiltonian analysis of given action and determine the number of physical degrees of freedom.
