چکیده
We prove that the Schäfer–Wayne short pulse equation (SPE) which describes the propagation of ultra-short optical pulses in nonlinear media is integrable. First, we discover a Lax pair of the SPE which turns out to be of the Wadati–Konno–Ichikawa type. Second, we construct a chain of transformations which relates the SPE with the sine-Gordon equation.

Se p 20 04 Light propagation in a Cole - Cole nonlinear medium via Burgers - Hopf equation
Recently, a new model of propagation of the light through the so-called weakly three-dimensional Cole-Cole nonlinear medium with short-range nonlocality has been proposed. In particular, it has been shown that in the geometrical optics limit, the model is integrable and it is governed by the dispersionless Veselov-Novikov (dVN) equation. Burgers-Hopf equation can be obtained as 1+1-dimensional ...

متن کاملIntegrable discretizations and self-adaptive moving mesh method for a coupled short pulse equation
In the present paper, integrable semi-discrete and fully discrete analogues of a coupled short pulse (CSP) equation are constructed. The key to the construction are the bilinear forms and determinant structure of the solutions of the CSP equation. We also construct N-soliton solutions for the semi-discrete and fully discrete analogues of the CSP equations in the form of Casorati determinants. I...
متن کاملExact solutions of the 2D Ginzburg-Landau equation by the first integral method
The first integral method is an efficient method for obtaining exact solutions of some nonlinear partial differential equations. This method can be applied to non integrable equations as well as to integrable ones. In this paper, the first integral method is used to construct exact solutions of the 2D Ginzburg-Landau equation.
متن کاملOn Integrability of the Vector Short Pulse Equation
Using the Painlevé analysis preceded by appropriate transformations of nonlinear systems under investigation, we discover two new cases in which the Pietrzyk–Kanattšikov–Bandelow vector short pulse equation must be integrable due to the results of the Painlevé test. One of those two cases is technologically important because it describes the propagation of polarized ultra-short light pulses in ...
