Abstract.

We present a brief overview of the basic concepts of the theory of spatial optical solitons, including the soliton stability in non-Kerr media, the instability-induced soliton dynamics, and collision of solitary waves in nonintegrable nonlinear models. 

Keywords:  Spatial optical soliton; self-focusing; linear stability; soliton collisions.
