W, Linear and Non-local \W-Algebras in Sp(4) Particle Model
J. Gomis, J. Herrero, K. Kamimura
We comment on relations between the linear W_{2,4}^{linear} algebra and non-linear W(2,4)$ algebra appearing in a Sp(4) particle mechanics model by using Lax equations. The appeara…
Finite W_3 Transformations in a Multi-time Approach
J. Gomis, J. Herrero, K. Kamimura +1
Classical {\W} transformations are discussed as restricted diffeomorphism transformations (\W-Diff) in two-dimensional space. We formulate them by using Riemannian geometry as…
Particle Mechanics Models with W-symmetries
J. Gomis, J. Herrero, K. Kamimura +1
We introduce a particle mechanics model with Sp() gauge invariance. Different partial gauge-fixings by means of sl(2) embeddings on the gauge algebra lead to reduced models whi…
Zero-curvature condition in two dimensions. Relativistic particle models and finite \W-transformations
J. Gomis, J. Herrero, K. Kamimura +1
A relation between an gauge particle model and the zero-curvature condition in a two-dimensional gauge theory is presented. For the case we construct finite \W-tra…
