Abstract
The discrete self-trapping (DST) equation models a coupled system of classical or quantum anharmonic oscillators. In this paper we review the physical motivations for this model, and describe some of the known solutions of the equation. The aim of this paper is to provide a basic introduction to other contributions to this volume covering recent results on the DST equation and its applications.
