Algebraic structures in exceptional geometry
Martin Cederwall
Exceptional field theory (EFT) gives a geometric underpinning of the U-duality symmetries of M-theory. In this talk I give an overview of the surprisingly rich algebraic structures…
Pure spinor superspace action for D=6, N=1 super-Yang-Mills theory
Martin Cederwall
A Batalin-Vilkovisky action for D=6, N=1 super-Yang--Mills theory, including coupling to hypermultiplets, is given. The formalism involves pure spinor superfields. The geometric pr…
Extended geometries
Martin Cederwall, Jakob Palmkvist
We present a unified and completely general formulation of extended geometry, characterised by a Kac-Moody algebra and a highest weight coordinate module. Generalised diffeomorphis…
Generalised diffeomorphisms for E
Guillaume Bossard, Martin Cederwall, Axel Kleinschmidt +2
We construct generalised diffeomorphisms for E exceptional field theory. The transformations, which like in the E case contain constrained local transformations, close when…
Bifurcation in Quantum Measurement
Karl-Erik Eriksson, Martin Cederwall, Kristian Lindgren +1
We present a generic model of (non-destructive) quantum measurement. Being formulated within reversible quantum mechanics, the model illustrates a mechanism of a measurement proces…
An off-shell superspace reformulation of D=4, N=4 super-Yang-Mills theory
Martin Cederwall
D=4, N=4 super-Yang-Mills theory has an off-shell superspace formulation in terms of pure spinor superfields, which is directly inherited from the D=10 theory. That superspace, in…
