DESCRIPTION:Title: <a href="https://researchseminars.org/talk/k-os/9/">Ske
 ins and algebras</a>\nby Hugh Morton (University of Liverpool) as part of 
 [K-OS] Knot online seminar\n\n\nAbstract\nI will look at some algebras bas
 ed on braids with a quadratic relation\, which are natural candidates for 
 Homfly skein theory models.\nThe main theme will be the use of braids in t
 hickened surfaces to construct algebras. These readily produce the Hecke a
 lgebras and the affine Hecke algebras of type A. I will point out a proble
 m in doing the same for the double affine Hecke algebras\, along with a wa
 y round it\, which also allows for extensions to the algebras by the use o
 f closed curves and tangles in addition to braids. This is part of recent 
 work with Peter Samuelson.\n
