Corrigendum: Determinantal formulae for the Casimir operators of inhomogeneous Lie algebras

Abstract

The author would like to correct some inaccuracy in formula (6), concerning the contraction of Casimir operators, which is wrong in the stated form. Let g � g� be a nontrivial contraction. Without loss of generality we can suppose that the contraction is given, over some basis, by a transformation of the type [1]
