Winding and Unwinding and Essential Intersections in
Jane Gilman, Linda Keen
Let be a non-elementary two generator subgroup of the isometry group of , the hyperbolic plane. If is discrete and free and geometricall…
Canonical Hexagons and the PSL(2,C) Discreteness Problem
Jane Gilman, Linda Keen
The discreteness problem, that is, the problem of determining whether or not a given finitely generated group G of orientation preserving isometries of hyperbolic three-space is di…
Cutting Sequences and Palindromes
Jane Gilman, Linda Keen
We give a unified geometric approach to some theorems about primitive elements and palindromes in free groups of rank 2. The geometric treatment gives new proofs of the theorems. D…
Enumerating Palindromes and Primitives in Rank Two Free Groups
Jane Gilman, Linda Keen
Let be a rank two free group. A word in is {\sl primitive} if it, along with another group element, generates the group. It is a {\sl palindrome} (with res…
