Title: “Moduli spaces of J-holomorphic curves” Speaker: Dusa McDuff, Columbia Date: Tuesday February 4 Time: 1:00pm Place: Lecture Hall 102, Simons Center [box, type=”download”]Watch the video.[/box] Abstract: This talk is aimed at nonspecialists, and will try to explain what the current Moduli Spaces program is hoping to achieve. Why are J-holomorphic curves important in symplectic topology today? What … Read more
Title: Minimal Discrepancy of Isolated Singularities and Reeb Orbits Continued Speaker: Mark McLean, MIT Date: Tuesday, February 4, 2014 Time: 11:15am-12:30pm Place: Seminar Room 313, Simons Center [box, type=”download”]Watch the video.[/box] Abstract: Recall from the previous lecture, if A is an isolated singularity satisfying additional conditions then there is an invariant md(A) called the minimal discrepancy. Also … Read more
