Extended near horizon symmetries of extremal BTZ black holes in 3D massive gravity

Abstract We study the asymptotic symmetries of near-horizon extremal BTZ black holes in higher derivative theories of gravity, such as New Massive Gravity and Topological Massive Gravity. By employing a particular boundary condition and the regularization prescription proposed earlier for the Einste...
