SUMMARY:Algebraic Graph Theory - Akihiro Munemasa
CLASS:PUBLIC
DESCRIPTION:TITLE: Abelian covers of association schemes with applications 
 to\nSIC-POVM\n\nSPEAKER:\n Akihiro Munemasa\n\nAFFILIATION:\n Tohoku Unive
 rsity\n\nLOCATION:\n Please contact Sabrina Lato for Zoom link.\n\nABSTR
 ACT: Godsil and Hensel (1992) developed a theory of abelian\ncovers of com
 plete graphs to construct antipodal distance-regular\ngraphs of diameter 3
 . More recently\, Coutinho\, Godsil\, Shirazi and\nZhan (2016) showed that
  equiangular tight frames can be constructed\nfrom covers of complete grap
 hs in terms of cyclic groups of prime\norder. In this talk\, we introduce 
 covers of (not necessarily\nsymmetric) association scheme of d classes in 
 terms of an (not\nnecessarily cyclic) abelian group G of order d.
