Research Group Low-Dimensional Topology

The double tangle of a trefoil and its Heegaard Floer invariant, taken from Zibrowius: Heegaard Floer multicurves of double tangles, Proceedings of Symposia in Pure Mathematics 109 (2024), 253–284 (arXiv:2212.08501 | doi:10.1090/pspum/109/01999)

Low-dimensional topology deals with spaces of dimensions 0 through 4. The particular research focus of our group lies on categorified knot invariants, such as knot Floer homology and Khovanov homology, and their application to topological problems.
