In this paper we introduce the concept of multi-soliton complexes MSC . A particular example of
a MSC is an incoherent soliton in a multimode fiber or in a photorefractive crystal, but there are
many examples in other areas of physics. We discuss a variety of profiles of MSCs, their unusual
collisional properties, the possibility of a MSC on a background and some other interesting
properties of MSCs. Some of their features are also shared by single solitons, but there are many
differences between the properties of the two types. 2000 American Institute of Physics.

The concept of the multi-soliton complex ,,MSC... is a very
useful notion in modern nonlinear science. In simple
terms, a multi-soliton complex is a self-localized state
which is a nonlinear superposition of several fundamen-
tal solitons. In optics, it can be a single beam or pulse
formed by a nonlinear superposition of fundamental soli-
tons, where each has the same velocity. The nonlinear
