The Informal Symplectic Geometry Seminar will make a brief re-appearance just after the end of this semester:

May 22, 10:30 a.m., in Math 507 | D. Thurston (Columbia) | HF-hat for 3-manifold with boundary I: a toy model. |

May 22, 2:00 p.m., in Math 507 | R. Lipshitz (Columbia) | HF-hat for 3-manifold with boundary II: Heegaard diagrams and holomorphic curves. |

May 23, 10:00 a.m., in Math 507 | P. Ozsváth (Columbia) | HF-hat for 3-manifold with boundary III: Computations and further structure. |

The Informal Symplectic Geometry Seminar should not be confused with Columbia's more traditional Symplectic Geometry and Gauge Theory seminar, which meets on Fridays.
