Heterotic Reduction of Courant Algebroid Connections and Einstein-Hilbert Actions

Jurco, Branislav, Vysoky, Jan

Understand

We discuss Levi-Civita connections on Courant algebroids.

  • We define an appropriate generalization of the curvature tensor and compute the corresponding scalar curvatures in the exact and heterotic case, leading to generalized (bosonic) Einstein-Hilbert type of actions known from supergravity.
  • In particular, we carefully analyze the process of the reduction for the generalized metric, connection, curvature tensor and the scalar curvature.
