RT info:eu-repo/semantics/article T1 Extended D = 3 Bargmann supergravity from a Lie algebra expansion A1 Azcárraga Feliu, José Adolfo de A1 Gútiez, Diego A1 Izquierdo Rodríguez, José Manuel AB In this paper we show how the method of Lie algebra expansions may be used to obtain, in a simpleway, both the extended Bargmann Lie superalgebra and the Chern-Simons action associated to it in threedimensions, starting from D = 3, N = 2 superPoincaré and its corresponding Chern-Simons supergravity.
