报告摘要：Ball swapping gives a geometric way to realize monodromy coming from motions in algebraic configuration spaces. I will explain this relation in the setting of Milnor fibers, briefly reviewing the known uniqueness results for the A-type Milnor fiber and then discussing the D-type case. The goal is to understand how configuration-space topology produces symplectic mapping classes via ball-swapping constructions. This is ongoing joint work with Jialiang Chen.
