25 p, 228.7 KB Combinatorial and metric properties of Thompson's group T / Burillo Puig, Josep ; Cleary, Sean ; Stein, Melanie ; Taback, Jennifer ; Centre de Recerca Matemàtica
We discuss metric and combinatorial properties of Thompson's group T, such as the normal forms for elements and uniqueness of tree pair diagrams. We relate these properties to those of Thompson's group F when possible, and highlight combinatorial differences between the two groups. [...]

27 p, 239.1 KB Bounding right-arm rotation distances / Cleary, Sean ; Taback, Jennifer ; Centre de Recerca Matemàtica
Rotation distance quantifies the difference in shape between two rooted binary trees of the same size by counting the minimum number of elementary changes needed to transform one tree to the other. We describe several types of rotation distance, and provide upper bounds on distances between trees with a fixed number of nodes with respect to each type. [...]

14 p, 177.3 KB Tree automorphisms and quasi-isometries of Thompson's group F / Cleary, Sean ; Taback, Jennifer ; Centre de Recerca Matemàtica
We prove that automorphisms of the infinite binary rooted tree T2 do not yield quasi-isometries of Thompson's group F, except for the map which reverses orientation on the unit interval, a natural outer automorphism of F. [...]
