Teoria Geométrica dos Grupos

Pré-requisitos: Basic group theory and Riemannian geometry

Topics: Groups and presentations: abelian groups, solvable groups, nilpotent groups, Jordan’s theorem, free groups and group presentations. Cayley graphs, coarse geometry, quasi-isometries, Gromov-hyperbolic spaces, hyperbolic groups, ideal boundaries and some further properties of hyperbolic groups. Coarse topology: metric cell complexes, the ends of a space, Rips complexes. Tits alternative. Growth of groups and Gromov’s theorem. Other proofs of Gromov’s theorem.
Further topics include: Quasi-isometries of nonuniform lattices in hyperbolic spaces, Schwartz Rigidity Theorem, Mostow Rigidity Theorem.
