| TITLE | [GS_M_Topo] Lefschetz fibrations on plumbings of $T^*S^n$ along trees |
| ABSTRACT | In this talk, I will give an algorithm producing Lefschetz fibrations defined on any plumbing space of $T^*S^n$s where the plumbing pattern is a tree. As a corollary, we can generate diffeomorphic families of plumbing spaces. This will help us to construct exotic families, or moreover, it helps us to understand the difference between smooth/differential topology and symplectic topology. |
