Newton-Hooke Algebras, Non-relativistic Branes and Generalized pp-wave Metrics

Jan Brugues, Joaquim Gomis, Kiyoshi Kamimura

The Newton-Hooke algebras in d dimensions are constructed as contractions of dS(AdS) algebras. Non-relativistic brane actions are WZ terms of these Newton-Hooke algebras. The NH al…
