-brane Galilean and Carrollian Geometries and Gravities
Eric Bergshoeff, José Figueroa-O'Farrill, Kevin van Helden +3
We study -dimensional -brane Galilean geometries via the intrinsic torsion of their adapted connections. These non-Lorentzian geometries are examples of -structures whose…

Generalized Newton-Cartan Geometries for Particles and Strings
Eric Bergshoeff, Kevin van Helden, Johannes Lahnsteiner +2
We discuss the generalized Newton-Cartan geometries that can serve as gravitational background fields for particles and strings. In order to enable us to define affine connections…
