چکیده
The perturbation theory based on the Riemann-Hilbert problem is developed for the modified nonlinear Schrödinger equation which describes the propagation of femtosecond optical pulses in nonlinear single-mode optical fibers. A detailed analysis of the adiabatic approximation to perturbation-induced evolution of the soliton parameters is given. The linear perturbation and the Raman gain are considered as examples.

The method of multiscale analysis is constructed for dicrete systems of evolution equations for which the problem is that of the far behavior of an input boundary datum. Discrete slow space variables are introduced in a general setting and the related finite differences are constructed. The method is applied to a series of representative examples: the Toda lattice, the nonlinear Klein-Gordon ch...

We argue that the integrable modified nonlinear Schrödinger equation with the nonlinearity dispersion term is the true starting point to analytically describe subpicosecond pulse dynamics in monomode fibers. Contrary to the known assertions, solitons of this equation are free of self-steepening and the breather formation is possible.

In this paper we reformulate free field theory models defined on the rectangular D+1 dimensional lattices as D + 1 evolution models. This evolution is in part a simple linear evolution on free (“creation” and “annihilation”) operators. Formal eigenvectors of this linear evolution can be directly constructed, and them play the role of the “physical” creation and annihilation operators. These ope...

Study of the nonlinear lattices ¨ q n = r(˙ q n)(g n+1 − g n), g n = g(q n − q n−1) (1) have brought Toda to the notion of dual system, which is obtained from the original one by " replacement of particles by springs and springs by particles accordingly to the certain rules " [1]. These rules are the following. The lattice (1) is equivalent to the Euler-Lagrange equations for the functional L =...
