In this Review we discuss three examples of different physical systems where the energy localization occurs at the edges due to nonlinearity, topology, or curvature. In many of such systems, the existence of localized edge modes and their properties can be verified experimentally, as for the case of arrays of weakly coupled optical waveguides.

Key words: edge modes, nonlinearity, topology, discrete systems.
