DESCRIPTION:Speaker: Andras Stipsicz\nhosted by Tamas Hausel\nAbstract: Kno
 t Floer homology (an invariant discovered by Peter Ozsvath\nand Zoltan Sza
 bo around 2001) provides a number of invariants \nto study knots\, links\,
  and relations among them.\nThe knot Floer chain complex (a slightly compl
 icated algebraic\nobject associated to a knot by the theory) can be used t
 o\ndefine these numerical invariants.\nMore recently\, in a joint project 
 with P. Ozsvath and Z. Szabo\,\nwe found a piecewise linear continuous fun
 ction (the Upsilon-function of \nthe knot) determined by the knot Floer ch
 ain complex.\nIn the lecture I plan to review the most important knot inva
 riants\,\nstarting with the Alexander polynomial. After the description of
  the\nknot Floer chain complex\, I will outline the definition of the\nUps
 ilon function\, and will present some simple applications.
