SUMMARY:Algebraic Graph Theory Seminar - Bill Martin
CLASS:PUBLIC
DESCRIPTION:TITLE: Polynomial ideals\, association schemes\, and the Q-pol
 ynomial\nproperty\n\nSpeaker:\n Bill Martin\n\nAfiliation:\n Worcester Pol
 ytechnic Institute\n\nZoom:\n Contact Sabrina Lato\n\nABSTRACT:\n\nLet X 
 ⊆ S^{m−1} be a spherical code in C^m. We study the ideal I\n⊆ C[z_1\
 , . . . \, z_m] of polynomials that vanish on the points of X:\nI = { F(z)
  | (∀a ∈ X) (F(a) = 0) }. The primary example of\ninterest is where th
 e Gram matrix of X is proportional to the first\nidempotent in some Q-poly
 nomial ordering of an association scheme (X\,\nR) defined on X.
