MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Jordan Szabo algebraic covariant derivative curvature tensors

Peter B. Gilkey, Raina Ivanova and Iva Stavrov

Abstract

We show that if $\nabla R$ is a Jordan Szabo algebraic covariant derivative curvature tensor on a vector space of signature (p,q) where q is odd and p is less than q or where q is congruent to 2 mod 4 and p is less than q-1, then $\nabla R$ vanishes. This algebraic result yields an elementary proof of the geometric fact that any pointwise totally isotropic pseudo-Riemannian manifold with such a signature (p,q) is locally symmetric
