Non-Riemannian isometries from double field theory
Chris D. A. Blair, Gerben Oling, Jeong-Hyuck Park
We explore the notion of isometries in non-Riemannian geometries. Such geometries include and generalise the backgrounds of non-relativistic string theory, and they can be naturall…
Galilean first-order formulation for the non-relativistic expansion of general relativity
Dennis Hansen, Jelle Hartong, Niels A. Obers +1
We reformulate the Palatini action for general relativity (GR) in terms of moving frames that exhibit local Galilean covariance in a large speed of light expansion. For this, we ex…
Spin Matrix Theory String Backgrounds and Penrose Limits of AdS/CFT
Troels Harmark, Jelle Hartong, Niels A. Obers +1
Spin Matrix theory (SMT) limits provide a way to capture the dynamics of the AdS/CFT correspondence near BPS bounds. On the string theory side, these limits result in non-relativis…
