| Aug 7, 2013 at 12:42 | comment | added | Victor | I vaguely remember there was some nice lemma in the book of Higman, Scott "Existentially closed groups" that two elements of a group are conjugate if and only if some system of group equations has a solution, and, I can't remember which one, but some of Higman's simple groups was used for that heavily. Sorry I don't have this book -- this is in Chapter 1 | |
| Aug 7, 2013 at 12:28 | comment | added | HJRW | I'd say that the usual technique for deciding this sort of question is to find a nice quotient in which the answer is 'obvious'. Since Higman's group has no finite quotients, and hence very few 'nice' quotients, this technique isn't going to work here. | |
