| Title: | Persistence of unknottedness of clean Lagrangian intersections |
| Speaker: | Johan Asplund, Stony Brook University |

| Abstract: | |
| Let L and K be two Lagrangian spheres in a six dimensional compact symplectic manifold that intersect cleanly along a circle. Assuming that the clean intersection is an unknot in both L and K, we will explain how the clean intersection must remain unknotted after any Hamiltonian isotopy of L and K that is supported near their union. This is based on joint work with Yin Li. | |
