Comments on Two-Loop Kac-Moody Algebras
Abstract
It is shown that the two-loop Kac-Moody algebra is equivalent to a two variable loop algebra and a decoupled β-γ system. Similarly WZNW and CSW models having as algebraic structure the Kac-Moody algebra are equivalent to an infinity of versions of the corresponding ordinary models and decoupled abelian fields.
