How to Tell if a Group Law Entails Virtual Nilpotence: Postscript
Abstract It is known that for any finitely generated group G from the large class of “locally graded” groups, satisfaction of an Engel or positive law forces G to be virtually nilpotent. Black (Citation1999) gives a sufficient condition for an arbitrary 2-variable law w(x, y)≡ 1 to imply virtual nilpotence—though …
