Abstract: |
Start with a two-variable complex polynomial $f$ with an isolated critical point at the origin. One can associate to it a smooth Riemann surface with boundary: the Milnor fiber of $f$, $M_f$, given by a smoothing of f near the origin. This comes equipped with a distinguished collection of $S^1$s on $M_f$, called vanishing cycles. We explain how an algorithm of A'Campo allows one to encode all of this information in a planar graph. Time allowing, we will explain how to associate a group to this graph, and discuss some of its representations. No prior knowledge of singularity theory will be assumed. |
