WebNov 27, 1998 · Lorentzian versions of classical Riemannian volume comparison theorems by Gunther, Bishop and Bishop-Gromov, are stated for suitable natural subsets of general semi-Riemannian manifolds. The problem is more subtle in the Bishop-Gromov case, which is extensively discussed. For the general semi-Riemannian case, a local version of the … WebFrom this volume comparison, we obtain similar results on the fundamental group as in [1,7,8]. 1.
