SUMMARY:Algebraic Graph Theory - John S. Caughman
CLASS:PUBLIC
DESCRIPTION:TITLE: Parameter constraints for distance-regular graphs that a
 fford\nspin models\n\nSPEAKER:\n John S. Caughman\n\nAFFILIATION:\n Portla
 nd State University\n\nLOCATION:\n Please contact Sabrina Lato for Zoom 
 link\n\nABSTRACT: In 1990\, Vaughn Jones introduced a link invariant\ncons
 tructed using matrices known as spin models. In 1996\, Francois\nJaeger di
 scovered that spin model matrices are contained in the\nBose-Mesner algebr
 a of an association scheme. Since many examples of\nassociation schemes ar
 ise from distance-regular graphs\, it is natural\nto ask which distance-re
 gular graphs afford a spin model.
