WebBefore going to examples, here are some general comments: a) Proving that a finitely generated group is Hopfian is usually pretty hard unless the group is residually finite e.g. finitely generated subgroups of G L ( n, R) are residually finite, hence Hopfian by an old result of Mal'cev. b) A common method in proving that a group G is co-Hopfian ... parenting topics for group therapyWebDefinition.
