| The concept of the soliton has been changing over the last decade or two. It changed from being a nonlinear mode of an integrable system to being described as a Hamiltonian soliton, and moreover, a dissipative soliton. The latter notion includes ultra-short pulses generated by laser systems, spatial solitons in wide aperture lasers dispersion managed solitons in all-optical systems with gain and loss and many other similar applications. This talk is aimed to reflect new items in the general list of solitons and to discuss their common features and differences from the traditional concept of solitons. |
