Duality-covariant particles and exotic branes
Josh O'Connor, David Osten
In this paper we construct duality-covariant worldvolume dynamics of particles and branes. We extend known actions and phase space formulations to include the hidden symmetry…

Generalised Cartan Geometry
David Osten
This talk introduces a Cartan-geometric framework for generalised geometries governed by a differential graded Lie algebra. In contrast to ordinary Cartan geometry, the tangent bun…

Gauged Extended Field Theory and Generalised Cartan Geometry
Falk Hassler, David Osten, Alex Swash
Cartan geometry provides a unifying algebraic construction of curvature and torsion, based on an underlying model Lie algebra -- a viewpoint that can be extended naturally to the h…
