Non-local Symmetries of Nonlinear Field Equations: an Algebraic Approach
M. Leo, R. A. Leo, G. Soliani +1
An algebraic method is devised to look for non-local symmetries of the pseudopotential type of nonlinear field equations. The method is based on the use of an infinite-dimensional…

Topological Field Theory and Nonlinear -Models on Symmetric Spaces
L. Martina, O. K. Pashaev, G. Soliani
We show that the classical non-abelian pure Chern-Simons action is related to nonrelativistic models in (2+1)-dimensions, via reductions of the gauge connection in Hermitian symmet…

Chern-Simons Quantum Field Representation of Planar Ferromagnets
L. Martina, O. K. Pashaev, G. Soliani
We represent the two - dimensional planar classical continuous Heisenberg spin model as a constrained Chern-Simons gauged nonlinear Schrödinger system. The hamiltonian structure of…
