Graded Lie superalgebras from embedding tensors
Sylvain Lavau, Jakob Palmkvist
We show how various constructions of -graded Lie superalgebras are related to each other. These Lie superalgebras have a Lie algebra as the subalgebra at…
Newton-Hooke/Carrollian expansions of (A)dS and Chern-Simons gravity
Joaquim Gomis, Axel Kleinschmidt, Jakob Palmkvist +1
We construct finite- and infinite-dimensional non-relativistic extensions of the Newton-Hooke and Carroll (A)dS algebras using the algebra expansion method, starting from the (anti…
Symmetries of post-Galilean expansions
Joaquim Gomis, Axel Kleinschmidt, Jakob Palmkvist +1
In this letter we study an infinite extension of the Galilei symmetry group in any dimension that can be thought of as a non-relativistic or post-Galilean expansion of the Poincare…
Tensor hierarchy algebras and extended geometry II: Gauge structure and dynamics
Martin Cederwall, Jakob Palmkvist
The recent investigation of the gauge structure of extended geometry is generalised to situations when ancillary transformations appear in the commutator of two generalised diffeom…
Tensor hierarchy algebras and extended geometry I: Construction of the algebra
Martin Cederwall, Jakob Palmkvist
Tensor hierarchy algebras constitute a class of non-contragredient Lie superalgebras, whose finite-dimensional members are the "Cartan-type" Lie superalgebras in Kac's classificati…
Infinity-enhancing of Leibniz algebras
Sylvain Lavau, Jakob Palmkvist
We establish a correspondence between infinity-enhanced Leibniz algebras, recently introduced in order to encode tensor hierarchies, and differential graded Lie algebras, which hav…
