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…
Holographic Plasmons
Ulf Gran, Marcus Tornsö, Tobias Zingg
Since holography yields exact results, even in situations where perturbation theory is not applicable, it is an ideal framework for modeling strongly correlated systems. We extend…
E in supergravity in four dimensions
Sudarshan Ananth, Lars Brink, Sucheta Majumdar
We argue that supergravity in four dimensions exhibits an exceptional symmetry, enhanced from the known invariance. Our procedure to demonstrat…
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…
All Killing Superalgebras for Warped AdS Backgrounds
S. Beck, U. Gran, J. Gutowski +1
We present all the symmetry superalgebras of all warped AdS, , flux backgrounds in dimensions preserving any number of supersymme…
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…
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…
Dualities in CHL-Models
Daniel Persson, Roberto Volpato
We define a very general class of CHL-models associated with any string theory (bosonic or supersymmetric) compactified on an internal CFT C x T^d. We take the orbifold by a pair (…
Gravitation and quadratic forms
Sudarshan Ananth, Lars Brink, Sucheta Majumdar +2
The light-cone Hamiltonians describing both pure Yang-Mills and N=4 super Yang-Mills may be expressed as quadratic forms. Here, we show that this feature extends to theories of gra…
BPS Algebras, Genus Zero, and the Heterotic Monster
Natalie M. Paquette, Daniel Persson, Roberto Volpato
In this note, we expand on some technical issues raised in \cite{PPV} by the authors, as well as providing a friendly introduction to and summary of our previous work. We construct…
