Seminar: Augmentations and link group representations

Seminar | Institute of Mathematical Sciences

Time:13:30-14:30, May 21, Tuesday

LocationRoom S507, IMS


Speaker: Honghao Gao, Fourier Institute (Grenoble, France)


Abstract: Given a framed link, paths in the link complement generate a non-commutative algebra as a link invariant, named the framed cord algebra. Augmentations are rank one representations of this algebra. We demonstrate how to construct a representation of the link group from an augmentation, and explain the story from symplectic geometry behind the construction.
