Limit groups for relatively hyperbolic groups, II: Makanin-Razborov diagrams

Groves, Daniel

Abstract

Let Γ be a torsion-free group which is hyperbolic relative to a collection of free abelian subgroups. We construct Makanin–Razborov diagrams for Γ. We also prove that every system of equations over Γ is equivalent to a finite subsystem, and a number of structural results about Γ–limit groups.
