Symplectic Topology Seminar: Nick Sheridan, “On the Fukaya Category of a Fano Hypersurface in Projective Space”

Title: On the Fukaya Category of a Fano Hypersurface in Projective Space Speaker: Nick Sheridan, Institute for Advanced Study Date: Tuesday, November 13, 2012 Time: 11:15am – 12:15pm Place: Seminar Room 313, Simons Center Abstract: We will outline a partial calculation of the Fukaya category of a Fano hypersurface in projective space. This gives us a proof of part of … Read more

Title: Large N Duality and Knot Contact Homology Speaker: Tobias Ekholm, Uppsala Date: Tuesday, November 6, 2012 Time: 11:15am – 12:15pm Place: Seminar Room 313, Simons Center     Abstract: Chern-Simons theory in the 3-sphere with Wilson loop observables along a link is related to the Gromov-Witten potential counting holomorphic disks on a Lagrangian filling of the conormal tori of the … Read more

Symplectic Topology Seminar: Frederic Bourgeois, “S^1-equivariant Symplectic Homology and Linearized Contact Homology”

Title: S^1-equivariant Symplectic Homology and Linearized Contact Homology Speaker: Frederic Bourgeois, Universite Libre de Bruxelles Date: Tuesday, November 6, 2012 Time: 10:00am – 11:00am Place: Seminar Room 313, Simons Center         Abstract: We define an S^1-equivariant version of symplectic homology via various equivalent approaches. We show that, over rational coefficients, S^1-equivariant symplectic homology is isomorphic to linearized contact homology. … Read more
