SUMMARY:Algebraic Graph Theory - Pierre-Antoine Bernard
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Bivariate P-polynomial Association Schemes 
 on the Fibers of\nUniform Posets\n\nSPEAKER:\n Pierre-Antoine Bernard\n\nA
 FFILIATION:\n Université de Montréal\n\nLOCATION:\n Please contact Sabri
 na Lato for the Zoom link.\n\nABSTRACT: Orthogonal polynomials emerging i
 n the context of P- and\nQ-polynomial association schemes are known to res
 ide within the\nAskey-scheme. This relationship forms a bridge between alg
 ebraic\ncombinatorics and the study of special functions\, yielding signif
 icant\nbenefits for both fields. Recent research has introduced multivaria
 te\ngeneralizations of P- and Q-polynomial association schemes and\nprovid
 ed numerous examples. This development aims notably to deepen\nour underst
 anding of multivariate analogues of Askey-Wilson\npolynomials. In this tal
 k\, we will review this generalization\, its\nconnection to m-distance-reg
 ular graphs\, and an algebraic\ncombinatorial structure known as a \"unifo
 rm poset\,\" from which many\nexamples of bivariate schemes appear to orig
 inate.\n
