Given a finitely generated (fg) group G, the set R(G) of homomorphisms from G to SL2C inherits the structure of an algebraic variety known as the representation variety of G in SL2C. This algebraic variety is an invariant of fg presentations of G. Call a group G parafree of rank n if it shares the lower central sequence with a free group of rank n, and if(More)
Given a finitely generated group G, the set Hom(G, SL2C) inherits the structure of an algebraic variety R(G) called the representation variety of G. This algebraic variety is an invariant of G. Let Gpt = 〈a, b; a p = b〉, where p, t are integers greater than one. In this paper a formula is produced yielding the number of four dimensional irreducible(More)
Hanna Neumann asked whether it was possible for two non-isomorphic residually nilpotent finitely generated (fg) groups, one of them free, to share the lower central sequence. G. Baumslag answered the question in the affirmative and thus gave rise to parafree groups. A group G is termed parafree of rank n if it is residually nilpotent and shares the same(More)
