Currents, charges and algebras in exceptional generalised geometry
David Osten
A classical -invariant Hamiltonian formulation of world-volume theories of half-BPS p-branes in type IIb and eleven-dimensional supergravity is proposed, extending known…

On current algebras, generalised fluxes and non-geometry
David Osten
A Hamiltonian formulation of the classical world-sheet theory in a generic, geometric or non-geometric, NSNS background is proposed. The essence of this formulation is a deformed c…

Generalised fluxes, Yang-Baxter deformations and the O(d,d) structure of non-abelian T-duality
Dieter Lust, David Osten
Based on the construction of Poisson-Lie T-dual -models from a common parent action we study a candidate for the non-abelian respectively Poisson-Lie T-duality group. This group…
