Abstract
Abstract We describe the general class of N-extended D = ( 2 + 1 ) Galilean supersymmetries obtained, respectively, from the N-extended D = 3 Poincare superalgebras with maximal sets of central charges. We confirm the consistency of supersymmetry with the presence of the ‘exotic’ second central charge θ. We show further how to introduce a N = 2 Galilean superfield equation describing nonrelativistic spin 0 and spin 1 2 free particles.
