Abstract
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.Keywords
