A general method is presented for reducing the problem of finding all continuous subgroups of a given Lie group, G, with a nontrivial invariant subgroup, N, to that of classifying the subgroups of N and the subgroups of the factor group G/N. The method is applied to classify all continuous subgroups of the Poincare group (PG) and of the Lorentz group extended by dilatations [the homogeneous similitude group (HSG)]. Lists of representatives of each conjugacy class of subalgebras of the Lie algebras of the groups PG and HSG are given in the form of tables. (5 tables) (auth)
