The de Sitter-invariant differential equations and their contraction to Poincaré and Galilei

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

We construct the second-order scalar differential equations invariant under the de Sitter, Poincaré and Galilei groups in two-dimensional space-time and show how they can be related by a group contraction procedure. A step toward a systematical study of this kind of relationship is presented.
