Abstract:
This talk will introduce a new invariant of tangles derived from Khovanov homology. As application, this may be used to construct an invariant of strong inversions of knots in the three-sphere and, in turn, produces an object that is quite sensitive to non-amphicheirality. Surprisingly, this new invariant picks up information that is not detected by the Jones polynomial or, more generally, Khovanov homologyv
