On the hardness of finding normal surfaces [PDF]
Journal of Applied and Computational Topology, 2021 For many fundamental problems in computational topology, such as unknot recognition and $3$-sphere recognition, the existence of a polynomial-time solution remains unknown. A major algorithmic tool behind some of the best known algorithms for these problems is normal surface theory.
