A nonlocal Poisson bracket of the sine-Gordon model
Andrei Mikhailov
It is well known that the classical string on a two-sphere is more or less equivalent to the sine-Gordon model. We consider the nonabelian dual of the classical string on a two-sph…
Baecklund transformations, energy shift and the plane wave limit
Andrei Mikhailov
We discuss basic properties of the Baecklund transformations for the classical string in AdS space in the context of the null-surface perturbation theory. We explain the relation b…
An action variable of the sine-Gordon model
Andrei Mikhailov
It was conjectured that the classical bosonic string in AdS times a sphere has a special action variable which corresponds to the length of the operator on the field theory side. W…
Plane wave limit of local conserved charges
Andrei Mikhailov
We study the plane wave limit of the Backlund transformations for the classical string in AdS space times a sphere and obtain an explicit expression for the local conserved charges…
