Generalised Bargmann Superalgebras
Ross Grassie
The Bargmann algebra and centrally-extended Newton-Hooke algebras describe the non-relativistic symmetries of massive particles in flat and curved spacetimes, respectively. These t…

Kinematical superspaces
José Figueroa-O'Farrill, Ross Grassie
We classify kinematical and aristotelian Lie superalgebras with spatial isotropy, but not necessarily parity nor time-reversal invariance. Employing a quaternionic fo…

Geometry and BMS Lie algebras of spatially isotropic homogeneous spacetimes
José Figueroa-O'Farrill, Ross Grassie, Stefan Prohazka
Simply-connected homogeneous spacetimes for kinematical and aristotelian Lie algebras (with space isotropy) have recently been classified in all dimensions. In this paper, we conti…
