Given a complex polynomial with an isolated singular point, one can associate to it a number of invariants belonging to symplectic geometry. The simplest is the Milnor fibre of this singularity: a smoothing of the fibre of the singular value, which naturally carries a symplectic structure. We will show that simple surface singularities (i.e. those of type ADE ) can by characterized by symplectic properties of their Milnor fibres. More generally, we will explain how revisiting classical singularity from the perspective of symplectic geometry, a program suggested by Arnol’d, can yield interesting results for both sides.

This talk will not assume any prior knowledge of symplectic geometry.
