Construction of Invariants for Lie Algebras of Inhomogeneous Pseudo‐Orthogonal and Pseudo‐Unitary Groups

A method of constructing invariants for the Lie algebras of the inhomogeneous pseudo‐orthogonal and pseudo‐unitary groups from invariants of the (homogeneous) pseudo‐orthogonal and pseudo‐unitary groups, respectively, is presented. The method is based on the ``expansion'' (or ``deformation'') of the inhomogeneous algebras to homogeneous ones. Several examples are worked out.
