Note About Non-Relativistic Diffeomorphism Invariant Gravity Action in Three Dimensions

Understand

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.
