Holomorphic supergravity in ten dimensions and anomaly cancellation
Anthony Ashmore, Javier José Murgas Ibarra, Charles Strickland-Constable +1
We formulate a ten-dimensional version of Kodaira-Spencer gravity on a Calabi-Yau five-fold that reproduces the classical Maurer-Cartan equation governing supersymmetric heterotic…
