A mathematical problem solved by Susanna Heikkilä relates to the classification of quasiregularly elliptic 4-manifolds, ...

The main result is that an s-cobordism (topological or smooth) of 4-manifolds has a product structure outside a "core" sub-s-cobordism. These cores are arranged to have quite a bit of structure, for ...

The past decade has seen trisections emerge as a transformative method for dissecting four-manifolds into three interlocking four-dimensional handlebodies. This approach, analogous to Heegaard ...
