Isotropic subbundles of TM ⊕ T*M

Research output: Contribution to journalArticlepeer-review

Abstract

We define integrable, big-isotropic structures on a manifold M as subbundles E ⊆ TM ⊕ T*M that are isotropic with respect to the natural, neutral metric (pairing) g of TM ⊕ T*M and are closed by Courant brackets (this also implies that [E, Eg] ⊆Eg). We give the interpretation of such a structure by objects of M, we discuss the local geometry of the structure and we give a reduction theorem.
