MATH Seminar: “Winding Homology of Knotoids”, Deniz Kutluay, 3:40PM February 18 (EN)

You are cordially invited to the ODTU-Bilkent Algebraic Geometry Seminar

Speaker: Deniz Kutluay (Indiana)
“Winding homology of knotoids”

Abstract: Knotoids were introduced by Turaev as open-ended knot-type diagrams that generalize knots. Turaev defined a two-variable polynomial invariant of knotoids generalizing the Jones knot polynomial to knotoids. We will give a construction of a triply-graded homological invariant of knotoids categorifying the Turaev polynomial, called the winding homology. Forgetting one of the three gradings gives a generalization of the Khovanov knot homology to knotoids. We will briefly review the basics of the theory of knotoids and also explain the notion of categorification which plays an important role in contemporary knot theory — no prior knowledge will be assumed.
