Using the integrability of sinh-Gordon equation, we demonstrate spectral stability its elliptic solutions. By constructing a Lyapunov functional using higher-order conserved quantities show that these solutions are orbitally stable with respect to subharmonic perturbations arbitrary period.

متن کاملOn noncommutative sinh-Gordon equation
We give a noncommutative extension of sinh-Gordon equation. We generalize a linear system and Lax representation of the sinh-Gordon equation in noncommutative space. This generalization gives a noncommutative version of the sinh-Gordon equation with extra constraints, which can be expressed as global conserved currents. PACS: 11.10.Nx, 02.30.Ik
