摘要：

We address the question of what geometric principle might be related to the W-algebras in the same way as the Virasoro algebra is connected with the diffeomorphisms of a Riemann surface. We suggest that a Kaluza-Klein-type approach on group-manifolds might provide some insight. We exhibit transformations of geometric origin forming an algebra that (a) is covariant, (b) can also be formulated for dimensions different from two, and (c) when restricted to D=2 and chiral transformation parameters, closely resembles the WN-algebras. © 1990.
