Abstract

We describe the algebra of matrices commuting with the action of the modular group on characters ofSU(N) k integrable representations. Using methods of finite quantum mechanics we find a canonical basis for this commutant over ℂ and prove the existence of an equivalent basis over ℚ with integral matrix elements. A final section is devoted to the case ofSU(3).
