Bivariate P -polynomial association schemes
Résumé
Bivariate P -polynomial association scheme of type (α, β) are defined as a generalization of the P -polynomial association schemes. This generalization is shown to be equivalent to a set of conditions on the intersection parameters. A number of known higher rank association schemes are seen to belong to this broad class. Bivariate Q-polynomial association schemes are similarly defined.
