- W2964891451 abstract "A bstract We show that an extended 3 D Schrödinger algebra introduced in [1] can be reformulated as a 3 D Poincaré algebra extended with an SO(2) R-symmetry generator and an SO(2) doublet of bosonic spin-1/2 generators whose commutator closes on 3 D translations and a central element. As such, a non-relativistic Chern-Simons theory based on the extended Schrödinger algebra studied in [1] can be reinterpreted as a relativistic Chern-Simons theory. The latter can be obtained by a contraction of the SU(1 , 2) × SU(1 , 2) Chern-Simons theory with a non principal embedding of SL(2 , ℝ ) into SU(1 , 2). The non-relativisic Schrödinger gravity of [1] and its extended Poincaré gravity counterpart are obtained by choosing different asymptotic (boundary) conditions in the Chern-Simons theory. We also consider extensions of a class of so-called l -conformal Galilean algebras, which includes the Schrödinger algebra as its member with l = 1 / 2, and construct ChernSimons higher-spin gravities based on these algebras." @default.
