the minimal genus problem is a fundamental question in smooth 4-manifold topology. every 2-dimensional homology class can be represented by a surface. but how small can this surface be? a generation ago, techniques from gauge theory were used to solve this in a large class of 4-manifolds with extra geometric structure, namely symplectic 4-manifolds. recent work on trisections if 4-manifolds has revealed a deep connection with symplectic geometry and gives a new perspective on this result.
