Abstract:We examine how the Einstein-Hilbert action is renormalized by adding the usual counterterms and additional corner counterterms when the boundary surface has corners. A bulk geometry asymptotic to H d+1 can have boundaries S k × H d−k and corners for 0 ≤ k < d. We show that the conformal anomaly when d is even is independent of k. When d is odd the renormalized action is a finite term that we show is independent of k when k is also odd. When k is even we were unable to extract the finite term using the countert… Show more
