Generalised $G_{2}$ -structures and type IIB superstrings

Claus Jeschek, Frederik Witt

The recent mathematical literature introduces generalised geometries which are defined by a reduction from the structure group $S O (d, d)$ of the vector bundle $T^{d} \oplus T^{d *}$ to…

Conformal properties of harmonic spinors and lightlike geodesics in signature $(1, 1)$

Frederik Witt

We are studying the harmonic and twistor equation on Lorentzian surfaces, that is a two dimensional orientable manifold with a metric of signature $(1, 1)$ . We will investigate the…

Generalised $G_{2}$ -manifolds

Frederik Witt

We define new Riemannian structures on 7-manifolds by a differential form of mixed degree which is the critical point of a (possibly constrained) variational problem over a fixed c…
