Homology and cohomology are ismorphic
Webto any perversity p. In the direction cohomology → homology, we obtain the isomorphism IH∗ p (X) = IHt−p ∗ X,X, where X p = [S S1 p(S1)<0 S = [p(S)<0 S. In the direction homology → cohomology, we obtain the isomorphism IHp ∗ (X) = IH∗ max(0,t−p) (X). In our paper stratified pseudomanifolds with one-codimensional strata are allowed. WebAbstract. The aim of this paper is two-fold. First, we give a fully geometric description of the HOMFLYPT homology of Khovanov-Rozansky. Our method is to construct this invariant
