We give a representation-theoretic interpretation of the sine-Gordon equation using the action of affine Kac-Moody algebra sl 2 on the Weyl algebra. In this setup t-functions become functions in non-commuting variables. The skew Casimir operators that we introduce here, give rise to a hierarchy of p
