Classical W-symmetry and Grassmannian Manifold
Yutaka Matsuo
Abstract
Classical W-symmetry is globally parametrized by the Grassmannian Manifold which is associated with the non-relativistic fermions. We give the bosonization rule which defines the natural higher coordinates system to describe the W-geometry. Generators of the W-algebra can be obtained from a single tau-function by using vertex operators.
