Classical BV cohomology of the spinning particle
Eugenia Boffo, Martin Cederwall
We show that the classical Batalin--Vilkovisky cohomology at negative ghost number of the spinning particle, observed in ref. arXiv:1511.02135, is removed by a Koszul--Tate resolut…
The octonionic phase space Hopf map
Martin Cederwall
The octonionic Hopf map, expressing as an bundle over , appears in the twistor transform in 10 dimensions, playing the rôle of the celestial sphere. A sym…
Some remarks on invariants
Martin Cederwall, Jessica Hutomo, Sergei M. Kuzenko +2
The demand to know the structure of functionally independent invariants of tensor fields arises in many problems of theoretical and mathematical physics, for instance for the const…
Non-associative structures in extended geometry
Martin Cederwall, Jakob Palmkvist
We consider a generalisation of vector fields on a vector space, where the vector space is generalised to a highest-weight module over a Kac-Moody algebra. The generalised vector f…
BV actions for extended geometry
Martin Cederwall
I review the construction of actions for extended geometry from the grading of an underlying tensor hierarchy algebra, which provides the full set of Batalin-Vilkovisky fields. The…
Gradient structures from extensions of over-extended Kac-Moody algebras
Martin Cederwall, Jakob Palmkvist
Over-extended Kac-Moody algebras contain so-called gradient structures - a gl(d)-covariant level decomposition of the algebra contains strings of modules at different levels that c…
