Milnor conjecture (knot theory)

In knot theory, the Milnor conjecture says that the slice genus of the

torus knot is It is in a similar vein to the Thom conjecture.

It was first proved by gauge theoretic methods by Peter Kronheimer and Tomasz Mrowka.

[1] Jacob Rasmussen later gave a purely combinatorial proof using Khovanov homology, by means of the s-invariant.
