The double tangle of a trefoil and its Heegaard Floer invariant

Research Group Low‑Dimensional Topology

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.
