Equivariance and finite type invariants in dimension 3
This thesis contains a study of finite type invariants of rational homology 3-spheres, and of null-homologous knots in these spheres. The main results are described in... -
Quasimorphisms on the braid groups and the Blanchfield form
In 2004, Gambaudo and Ghys proved a formula establishing a connection between the ω-signatures of a link and the symplectic features of a representation of the braid...
