DESCRIPTION:[b]Speaker: Peter Samuelson [/b](UC Riverside) [nl][nl]\n[b]Ab
 stract:[/b][nl]The Homflypt skein relations were originally used in the 9
 0's to define polynomial invariants of knots in S^3. In this talk we desc
 ribe several other ways they arise in algebra and geometry: intertwiners 
 for certain quantum group representations\, commutator relations in quant
 um groups\, deformation quantization of trace functions on character vari
 eties\, commutator relations in Hall algebras of Fukaya categories of sur
 faces\, and higher dimensional Heegaard-Floer homology of configuration s
 paces of points in cotangent bundles to surfaces. This will be a survey s
 tyle talk\; in particular\, no significant prior knowledge of these topic
 s will be assumed\, and the precision of the statements will decrease mon
 otonically as the talk progresses. Our main goal is to describe a nonobvi
 ous common theme in these topics.\n[nl]\n[nl]
