Fork Algebras in Algebra, Logic and Computer Science

Fork algebras are a formalism based on the relational calculus, with interesting algebraic and metalogical properties. Their representability is especially appealing in computer science, since it allows a closer relationship between their language and models. This work gives a careful account of the results and presents some applications of Fork algebras in computer science, particularly in system specification and program construction. Many applications of Fork algebras in formal methods are foreseen, and the work covers all the essentials in order to provide the reader with a better understanding.
