WebNov 17, 2024 · Instanton knot homology was first introduced by Floer around 1990 and was revisited by Kronheimer and Mrowka around 2010. It is built based on the solution to a set of partial differential equations and is very difficult to compute. On the other hand, Heegaard diagrams are classical tools to describe knots and 3-manifolds combinatorially, and is … WebIt is well known that the first homology group of a knot complement R ∖ K is isomorphic to the integers Z (which can also be computed using a Mayer-Vietoris sequence), and so the … WebThe Floer homology group KHI.K/is supposed to be an “instanton” counterpart to the Heegaard knot homology of Ozsvath-Szab´ o and Ras-´ mussen [12,13].
