Ég minni á málstofuna á eftir.
Dagsetning: Mánudagur 3. september 2012 kl 3.
Staður: VRII herbergi 158.
Fyrirlesari: Grace Kennedy, University of Santa Barbara
Titill: A Diagrammatic Multivariate Alexander Invariant of Tangles
Ágrip:
Recently, Bigelow defined a diagrammatic method for calculating the
Alexander polynomial of a knot or link by resolving crossings in a planar
algebra. I will present my multivariate version of Bigelow's calculation.
The advantage to my algorithm is that it generalizes to a multivariate
tangle invariant up to Reidemeister I.
