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.

Generalized plane wave manifolds

Peter B. Gilkey and Stana Nikcevic

Abstract

We show that generalized plane wave manifolds are complete, strongly geodesically convex, Osserman, Szabo, and Ivanov-Petrova. We show their holonomy groups are nilpotent and that all the local Weyl scalar invariants of these manifolds vanish. We construct isometry invariants which are not of Weyl type. Given k, we exhibit manifolds in this family which are k-curvature homogeneous but not locally homogeneous. We also exhibit a manifold which is weakly 1-curvature homogeneous but not 1-curvature homogeneous.
