The book is divided into three chapters. We begin with the definition of Morita context rings in Chapter 1, then list examples from classical matrix algebras, path algebras, smash product, groups algebras and operator algebras. In Chapter 2, we study linear mappings on Morita context rings, including commuting mappings, Lie derivations, Jordan derivations, Jordan generalized derivations and Lie triple derivations. Chapter 3 is devoted to the treatment of higher derivations and non-linear mappings.
