Abstract
All the connected subgroups of the Galilei group G—and of its central extension G̃—are determined and classified up to a conjugation of G—respectively G̃—and also up to an isomorphism. In order to construct these subgroups, some general properties on subalgebras of a given Lie algebra have been proved. It is interesting to note that the subgroups of G̃ are derived from the subgroups of G.Keywords
