DESCRIPTION:Speaker: Maria Chlouveraki\nhosted by Tamas Hausel\nAbstract: I
 n the 1960’s\, Yokonuma introduced certain algebras as generalisations of
  the Iwahori-Hecke algebras in the context of finite reductive groups\; th
 ese algebras are now called Yokonuma-Hecke algebras. In the 1980’s\, Jone
 s used the Markov trace on the Iwahori-Hecke algebra of type A in order to
  define knot invariants. His method gave rise to famous polynomial knot in
 variants such as the Jones polynomial and the Homflypt polynomial (else kn
 own as 2-variable Jones polynomial). In the past years\, Juyumaya and Lamb
 ropoulou similarly used the Markov trace on the Yokonuma-Hecke algebra of 
 type A in order to define invariants for framed and classical knots. In a 
 joint work with Juyumaya\, Karvounis and Lambropoulou\, we showed that the
  latter are not equivalent to the Homflypt polynomial. In this talk\, I wi
 ll discuss the above results\, as well as some interesting properties of t
 he newly constructed invariants.\n
