摘要
The contraction method in different limits to obtain 22 different realizations of kinematical algebras isapplied to study the supersymmetric extension of AdS algebra and its contractions. It is shown that p2 h p＇, c2 and g＇ algebras, in addition to d_, p, n_, g and c algebras, have supersymmetric extension, while n-2, g2 and g＇2 algebras have no supersymmetric extension. The connections among the superalgebras are established.
