Knots and Surfaces in four-manifolds
Four-dimensional smooth manifolds show very different behaviour than manifolds in any other dimension. In fact, in other dimensions we have a somewhat clear picture of the classification, while dimension four is still elusive. The project aims to further our knowledge in this question in several ways. The genus function, and its enhanced version taking knots and their slice surfaces into account, plays a crucial role in understanding different smooth structures on four-manifolds. Techniques for studying these objects range from topological and symplectic/algebraic geometric (on the constructive side) to algebraic and analytic methods resting on specific PDE’s and on counting their solutions…
