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. We discuss the analogous action variable in the sine-Gordon model. We explain the relation between this action variable and the Backlund transformations and show that the corresponding hidden symmetry acts on
The Hamiltonian version of the sine-Gordon equation (in case (1), for example) is the Hamiltonian system with Hamiltonian. P 0 = 1 γ ∫ − ∞ + ∞ ( 1 2 π 2 ( x) − 1 2 ( ∂ u ∂ x) 2 + m 2 ( 1 − cos. . u)) d x, γ > 0, and symplectic form. Ω = 1 γ ∫ − ∞ + ∞ d π ( x) ∧ d u ( x) d x, π = ∂ u ∂ t.

Re-scaled Action for the sine-Gordon model. Renormalization group flows equations of the sine Equations (1) and (2) are actually the solutions to these PDEs. (BTW, in Eq.(2), it should be trigonometric arctangent, not the hyperbolic one). One can obtain a $\phi^4$ model as an approximation of the sine-Gordon model, expanding the sine term in the equation or cosine term in the Hamiltonian.

Discrete sine-Gordon dynamics on networks, Submitted, 2016 Abstract. The paper develops an algebrotopological approach to the problem of effective selection of real finite-zone solutions of the sine-Gordon equation, which uses the socalledγ-representation on the Riemann surface, in which “action” variables can be computed explicitly. We propose an action for a sine-Gordon-like theory, which reproduces the classical equations of motion of the Green-Schwarz-Metsaev-Tseytlin superstring on AdS5 × S^5. The action is relativistically invariant.

The power and the spectral composition of the perturbation-induced emission from a breather are calculated. It is demonstrated that the spectrum consists of separate lines, their intensity and width being exponentially small with respect to the breather's amplitude. The centers of the lines undergo the slow systematic drift.
