On Link Homology Theories from Extended Cobordisms
Abstract. This paper is devoted to the study of algebraic structures leading to link homology theories. The originally used structures of Frobenius algebra and/or TQFT are modified in two directions. First, we refine 2–dimensional cobordisms by taking into account their embedding into R. Secondly, we extend the underlying cobordism category to a 2–category, where the usual relations hold up to ...
متن کاملAn invariant of link cobordisms from Khovanov homology
Abstract In [10], Mikhail Khovanov constructed a homology theory for oriented links, whose graded Euler characteristic is the Jones polynomial. He also explained how every link cobordism between two links induces a homomorphism between their homology groups, and he conjectured the invariance (up to sign) of this homomorphism under ambient isotopy of the link cobordism. In this paper we prove th...
متن کاملAn Invariant of Link Cobordisms from Khovanov’s Homology Theory
i,j(−1) q rkH (D) is the Jones polynomial of L. The groups H (D) were defined as homology groups of a bigraded chain complex. Khovanov proved that the homology groups considered up to isomorphism depend only on the link L. In fact, he showed that any Reidemeister move induces a chain equivalence (of bidegree (0, 0)) between the chain complexes of the two diagrams involved. Khovanov acknowledged...
متن کاملLink Homology Theories from Symplectic Geometry
For each positive integer n, Khovanov and Rozansky constructed an invariant of links in the form of a doubly-graded cohomology theory whose Euler characteristic is the sl(n) link polynomial. We use Lagrangian Floer cohomology on some suitable affine varieties to build a similar series of link invariants, and we conjecture them to be equal to those of Khovanov and Rozansky after a collapse of th...
متن کاملKhovanov’s Homology for Tangles and Cobordisms
We give a fresh introduction to the Khovanov Homology theory for knots and links, with special emphasis on its extension to tangles, cobordisms and 2-knots. By staying within a world of topological pictures a little longer than in other articles on the subject, the required extension becomes essentially tautological. And then a simple application of an appropriate functor (a “TQFT”) to our pict...
