A model of soliton–defect interactions in the sine-Gordon equations is studied using singular perturbation theory. Melnikov …

We consider the interaction of a nonlinear Schrödinger soliton with a spatially localized (point) defect in the medium through which it …

We study a model derived by Fei et al. [Phys. Rev. A 45 (1992) 6019] of a kink solution to the sine-Gordon equation interacting with an …

Gap solitons are localized nonlinear coherent states that have been shown both theoretically and experimentally to propagate in …

We study models of Fei et al. and of Forinash et al of kinks in the sine-Gordon equation, and solitons in the nonlinear Schrodinger …

Downstream development is a term encompassinga variety of effects relating to the propagation of storm systems at midlatitude. We …

We consider the nonlinear propagation of light in an optical fiber waveguide as modeled by the anharmonic Maxwell-Lorentz equations …

We consider the model of catalysis due to Ziff, Gulari, and Barshad [Phys Rev. Lett. 56, 2553 (1986)] as a pattern formation problem. …
