Tensorial Constraints for Commuting Endomorphisms of the Generalized Tangent Bundle

Abstract

In this paper we consider families of mutually commuting endomorphisms of the generalized tangent bundle. We identify natural tensorial constraints extending the notion of a generalized Kähler structure to endomorphisms that are not necessarily generalized almost complex structures. These tensors form ideals whose generators we explicitly construct and study using Gröbner basis techniques.
