Khovanov homology and star-like isotopies

A star-like isotopy for oriented links in 3-space is an isotopy which uses only Reidemeister moves which correspond to the following singularities of planar curves:, , , .Full-size tableTable optionsView in workspaceDownload as CSVWe define a link polynomial derived from the Jones polynomial which is, in general, only invariant under star-like isotopies and we categorify it.
