Complete Integrable O(3)-σModel and r,s-Matrices

  • The fundamental Poisson structure of nonlinear O(3)-σmodel,treated as a constrained dynamical system, is discussed in arbitary local coordinate frame.The corrsponding r,s-matrices,which are generally field dependent,are presented explicitly.It is noticed,however, that in a certain local coordinate frame,r,s-matrices will be field-independent.

Abstract: The fundamental Poisson structure of nonlinear O(3)-σmodel,treated as a constrained dynamical system, is discussed in arbitary local coordinate frame.The corrsponding r,s-matrices,which are generally field dependent,are presented explicitly.It is noticed,however, that in a certain local coordinate frame,r,s-matrices will be field-independent.
