Abstract
It is shown in this letter that in the bosonic coset models G(k1) x G( k2)/G(k1+k2) associated with noncompact Kac-Moody algebra there exist two kinds of topological points, k2 = 0 and ki + k2 - 2g = 0. At these points, the coset models may be interpreted as twisted versions of no ncompact counterparts of the Kazama-Suzuki models.
