Abstract

We construct a sequence of Markov processes on the set of dominant weights of the Affine Lie algebra \mathfraksl2(\C) which involves tensor product of irreducible highest weight modules of \mathfraksl2(\C) and show that it converges towards a Doob's space-time harmonic transformation of a space-time Brownian motion.
