Geometric Makanin algorithm for solving equations in virtually free groups
Thursday November 8, 2007
09:00AM - 09:50AM
Speakers:
Vincent Guirardel
Abstract:
We give an algorithm deciding whether a system of equations and inequations in a virtually free group has a solution. This is done by giving a new geometric proof of Makanin’s algorithm, based on Rips theory for foliated 2-complexes. Applications include the solution of equations in hyperbolic groups, and the isomorphism problem between hyperbolic group in presence of torsion. This is a joint work with François Dahmani.
