The Initial Value Problem for the Generalised Einstein Equations
Oskar Schiller
We discuss the initial value problem for the Einstein equations in Hitchin's generalised geometry for the case of closed divergence (which correspond to the equations of motion in…

The canonical generalised Levi-Civita connection and its curvature
Vicente Cortés, Matas Mackevicius, Thomas Mohaupt +1
Given a (semi-Riemannian) generalised metric and a divergence operator on an exact Courant algebroid , we geometrically construct a canonical general…

Exterior Generalised Geometry
Vicente Cortés, Oskar Schiller
It is the aim of this paper to transfer to generalised geometry tools employed in the study of semi-Riemannian immersions, specializing at times to semi-Riemannian hypersurfaces. G…
