Geodesic orbit and naturally reductive nilmanifolds associated with graphs

Differential Geometry 2018-10-19 v1

Abstract

We study Riemannian nilmanifolds associated with graphs. We prove that such a nilmanifold is geodesic orbit if and only if it is naturally reductive if and only if its defining graph is the disjoint union of complete graphs and the left-invariant metric is generated by a certain naturally defined inner product.
