This is an introductory survey on multi-component nonlinear Schrödinger equations related to simple Lie algebras and symmetric spaces. These generalizations of the nonlinear Schrödinger equation were proposed by Fordy and Kulish in the early 1990’s. Recently, the authors sytematically studied these equations, their reductions and soliton solutions [Inverse Probl. 17, No. 4, 999–1015 (2001; Zbl 0988.35143
) and J. Phys. A, Math. Gen. 34, No. 44, 9425–9461 (2001; Zbl 1001.37074
)]. In particular, some of their results on this subject are reviewed and discussed in this paper.
