Three-dimensional non-relativistic (super)gravity and higher spins
Abstract:
In this talk, I will motivate and give an overview of
recent constructions of diffeomorphism-covariant non-relativistic
gravity and supergravity theories in three dimensions. Specific
emphasis will be put on the underlying space-time symmetry algebras
and how they can be viewed as Inönü-Wigner contractions or expansions
of the three-dimensional (super-)Poincare algebra. Towards the end, I
will mention generalizations to non-relativistic higher-spin
theories.
