A counterexample to the deformation conjecture for uniform tree lattices
1995
Proceedings of the American Mathematical Society
Preserved Fulltext
Let X be a universal cover of a finite connected graph. A uniform lattice on A' is a group acting discretely and cocompactly on X . We provide a counterexample to Bass and Kulkarni's Deformation Conjecture (1990) that a discrete subgroup F < Aut(^) could be deformed, outside some F-invariant subtree, into a uniform lattice.
