摘要：

We provide an explicit construction of the W3 extended conformal algebra starting from the affine algebra A2(1). Starting with the current algebra of A2(1) we prove, by explicit construction, that the cohomology of a BRST operator associated to a set of first-class constraints admits a representation of W3. We prove this at the level of operator algebras with the help of a free field representation for A2(1).
