A functor-valued invariant of tangles

Open access
Khovanov, Mikhail·2002·Algebraic & Geometric Topology

Abstract

We construct a family of rings.To a plane diagram of a tangle we associate a complex of bimodules over these rings.Chain homotopy equivalence class of this complex is an invariant of the tangle.On the level of Grothendieck groups this invariant descends to the Kauffman bracket of the tangle.When the tangle is a link, the invariant specializes to the bigraded cohomology theory introduced in our earlier work.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
