A note on Canonical Ricci forms on 2-step nilmanifolds

Differential Geometry 2014-05-26 v4

Abstract

In this note we prove that any left-invariant almost Hermitian structure on a 2-step nilmanifold is Ricci-flat with respect to the Chern connection and that it is Ricci-flat with respect to another canonical connection if and only if it is cosymplectic.
