The strongest genuinely computable knot invariant in 2024
Speaker: Professor Dror Bar-Natan
Affiliation: University of Toronto (Canada)
Abstract
"Genuinely computable" means we have computed it for random knots with over 300 crossings. "Strongest" means it separates prime knots with up to 15 crossings better than the less-computable HOMFLY-PT and Khovanov homology taken together. And hey, it's also meaningful and fun.
