Phys. Rev. D 75, 024009 (2007) [5 pages]General relativity from a gauged Wess-Zumino-Witten termReceived 18 October 2006; published 8 January 2007 In this paper two things are done. First it is shown how a four-dimensional gauged Wess-Zumino-Witten term arises from the five-dimensional Einstein-Hilbert plus Gauss-Bonnet Lagrangian with a special choice of the coefficients. Second, the way in which the equations of motion of four-dimensional General Relativity arise is exhibited. © 2007 The American Physical Society URL:
