Thresholds for breather solutions on the Discrete Nonlinear Schrödinger Equation with saturable and power nonlinearity

By Javier Cuevas and others
We consider the question of existence of periodic solutions (called breather solutions or discrete solitons) for the Discrete Nonlinear Schr\"odinger Equation with saturable and power nonlinearity. Theoretical and numerical results are proved concerning the existence and nonexistence of periodic solutions by a variational approach and a fixed point argument. In... Show more
