Abstract

Recently, Rips produced an example of a double of two free groups which has unsolvable generalized word problem. In this paper, we show that Rips's example fits into a large class of doubles of groups, each member of which contains F2×F2 and therefore has unsolvable generalized word problem and is incoherent. © 2001 Elsevier Science B.V.
