Abstract: The interplay between geometry and nonlinearity is a topic of great experimental and theoretical concern in several fields of modern physics, such as nonlinear optics, polaron formation in solid-states materials, and energy transport in organic thin films. We investigate the properties of nonlinear excitations in different types of soliton bearing systems with long-range dispersive interaction. We show that length-scale competition in such systems universally results into the multi-component structure of nonlinear excitations and can lead, in particular, to a diversity of multistability phenomena.
