    Chern-Simons gravity and holographic anomalies -: art. no. 039
    (2004) Bañados, M; Schwimmer, A; Theisen, S
    We present a holographic treatment of Chern-Simons (CS) gravity theories in odd dimensions. We construct the associated holographic stress tensor and calculate the Weyl anomalies of the dual CFT.

    Counterterms and dual holographic anomalies in CS gravity -: art. no. 067
    (2005) Bañados, M; Olea, R; Theisen, S
    The holographic Weyl anomaly associated to Chern-Simons gravity in 2n + 1 dimensions is proportional to the Euler term in 2n dimensions, with no contributions from the Weyl tensor. We compute the holographic energy-momentum tensor associated to Chern-Simons gravity directly from the action, in an arbitrary odd-dimensional spacetime. We show, in particular, that the counterterms rendering the action finite contain only terms of the Lovelock type.
