From pp-Waves to Galilean Spacetimes
José Figueroa-O'Farrill, Ross Grassie, Stefan Prohazka
We exhibit all spatially isotropic homogeneous Galilean spacetimes of dimension , including the novel torsional ones, as null reductions of homogeneous pp-wave spacet…

Lifshitz symmetry: Lie algebras, spacetimes and particles
José Figueroa-O'Farrill, Ross Grassie, Stefan Prohazka
We study and classify Lie algebras, homogeneous spacetimes and coadjoint orbits ("particles") of Lie groups generated by spatial rotations, temporal and spatial translations and an…
