Webcalled “vacuum,” of this Grassmann variety is chosen. This vacuum is “dressed” by a Laurent serires φ(z) to become a point of the Grassmann variety that corresponds to a general solution of the Landau-Lifshitz hierarchy. The Landau-Lifshitz hier-archy is thereby mapped to a simple dynamical system on the set of these dressed vacua. http://www.neo-classical-physics.info/uploads/3/0/6/5/3065888/burali-forti_-_grassman_and_proj._geom..pdf
