Ünal, Bülent Divergence theorems in semi-Riemannian geometry. (English) Zbl 0832.53050 Acta Appl. Math. 40, No.2, 173-178 (1995). From the author’s introduction: “In this paper, we will define a nondegenerate boundary of a semi-Riemannian manifold, and by making use of the volume form on the nondegenerate boundary, we will obtain two versions of the divergence theorem which are somewhat different from its usual form. And finally, we will state a version of the divergence theorem for two-dimensional Minkowski space”.Reviewer: A.V.Borisov (Sofia) Cited in 1 ReviewCited in 3 Documents MSC:53C50Lorentz manifolds, manifolds with indefinite metricsKeywords:nondegenerate boundary; volume form; divergence theorem BibTeX Full Text: DOI References:  Abraham, R., Marsden, J.
