| Abstract: | We study supersymmetric extensions of classical kinematical algebras from the point of view of contraction theory. It is shown
that contracting the supersymmetric extension of the anti-de Sitter algebra leads to a hierarchy similar in structure to the
classical Bacry—Lévy-Leblond classification. |
