Title: Coarse differentiation of quasi-isometries and rigidity for solvable groups
Abstract: In the early 80's Gromov initiated a program to study finitely generated groups up to quasi-isometry. This program was motivated by rigidity properties of lattices in Lie groups. A lattice Γ in a group G is a discrete subgroup where the quotient G/Γ has finite volume. Gromov's own major theorem in this direction is a rigidity result for lattices in nilpotent Lie groups. |
