Cayley-Klein contractions of orthosymplectic superalgebras

Abstract

We define a class of orthosymplectic superalgebras $osp(m;j|2n;\omega )$ which may be obtained from $osp(m|2n)$ by contractions and analytic continuations in a similar way as the orthogonal and the symplectic Cayley-Klein algebras are obtained from the corresponding classical ones. Contractions of $osp(1|2)$ and $osp(3|2)$ are regarded as an examples.
