Lee-Wald charge and asymptotic behaviors of the Weyl-invariant topologically massive gravity

We apply the Lee-Wald covariant phase space method to the Weyl-invariant topologically massive gravity and compute the corresponding on-shell conserved charges. By using appropriate decay conditions for the existing propagating modes in the near-horizon of a stationary black hole, we obtain the charges generating the asymptotic symmetries. We show that the charges are integrable and the (modified) algebras among the asymptotic generators areclosedfor the certain choice of central extensions.
