Beschreibung:
We characterize the integrability of various structures on Courant algebroids in terms of torsion-free generalized connections.The applications include generalized K\"ahler and generalized hyper-K\“ahler structures as particular examples. We do also give a spinorial characterization in the case of regular Courant algebroids. This is based on the theory of Dirac generating operators, for which we develop a new approach based on the geometric data encoding the regular Courant algebroid.This is joint work with Liana David, see arXiv:1905.01977.
