翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Free-by-cyclic group ： ウィキペディア英語版 Free-by-cyclic group In group theory, a group $G$ is said to be free-by-cyclic if it has a free normal subgroup $F$ such that the quotient group :$G/F$ is cyclic. In other words, $G$ is free-by-cyclic if it can be expressed as a group extension of a free group by a cyclic group (NB there are two conventions for 'by'). If $F$ is a finitely generated group we say that $G$ is ''(finitely generated free)-by-cyclic'' (or (f.g. free)-by-cyclic). ==References== * A. Martino and E.
