Kodaira-Spencer theory for flux backgrounds

Caleb Jonker, Julian Kupka, Ingmar Saberi +2

We give an explicit description (in component fields) of a holomorphic theory associated to a general supersymmetric background of supergravity in ten dimensions. Co…

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…

Kodaira-Spencer theory for Courant algebroids

Julian Kupka, Ingmar Saberi, Charles Strickland-Constable +1

Studying Courant algebroids on dg ringed manifolds, we observe that the associated Roytenberg-Weinstein algebra admits a local structure reminiscent of a shifted contact…

Geometry of supergravity and the Batalin--Vilkovisky formulation of the theory in ten dimensions

Julian Kupka, Charles Strickland-Constable, Fridrich Valach

We provide full details of a BV formulation of supergravity in ten dimensions, to all orders in fermions, built from the generalised geometry description of the theo…

Higher fermions in supergravity

Julian Kupka, Charles Strickland-Constable, Fridrich Valach

We show that the generalised geometry formalism provides a new approach to the description of higher-fermion terms in supergravity in ten dimensions, which does not…

Direct derivation of supergravity in ten dimensions to all orders in fermions

Julian Kupka, Charles Strickland-Constable, Fridrich Valach

It has been known for some time that generalised geometry provides a particularly elegant rewriting of the action and symmetries of 10-dimensional supergravity theories, up to the…
