Beltrami–McKeon–Schubert Realizations of (1|4) Algebra and Possible Supersymmetric Kinematics*

Abstract

Abstract The possible supersymmetric kinematics are presented by the contraction method in different limits from Beltrami–McKeon–Schubert realizations of (1|4). The connections among the superalgebras are established. The comparison with the superalgebras contracted from Beltrami–Ivanov–Sorini realization is made.
