Romans massive QP manifolds
Alex S. Arvanitakis, Emanuel Malek, David Tennyson
We introduce QP manifolds that capture the generalised geometry of type IIA string backgrounds with Ramond-Ramond fluxes and Romans mass. Each of these is associated to a BPS brane…

Exceptional complex structures and the hypermultiplet moduli of 5d Minkowski compactifications of M-theory
David Tennyson, Daniel Waldram
We present a detailed study of a new mathematical object in generalised geometry called an `exceptional complex structure' (ECS). It is the…

Heterotic backgrounds via generalised geometry: moment maps and moduli
Anthony Ashmore, Charles Strickland-Constable, David Tennyson +1
We describe the geometry of generic heterotic backgrounds preserving minimal supersymmetry in four dimensions using the language of generalised geometry. They are characterised by…
