The Virtual Surjection Conjecture for Discrete Groups

Algebra · posed by Martin Bridson, James Howie, Charles Miller III, Hamish Short, 2013 · solved

1 attempt

Statement

If a subgroup of a product of groups of type FkF_k virtually surjects onto every kk-tuple of factors, must it be of type FkF_k itself? Yes, for discrete groups, and likewise for FPkFP_k. The homological nn-(n+1)(n+1)-(n+2)(n+2) Conjecture follows for discrete groups when the common quotient is finitely presented, and that hypothesis cannot be dropped.

Context

A named conjecture on finiteness properties of subgroups of direct products, standard in geometric group theory alongside the n-(n+1)-(n+2) conjecture it implies.
