The paper presents an extensive set of mathematical propositions and proofs demonstrating the power of expression of the theory of constructions as introduced earlier by the authors. Constructions are well-typed expressions of the typed lambda-calculus with the types being lambda-expressions of the same nature. The apparatus was inspired by de Bruin’s Automath, Girard’s second-order types and Martin-Löf’s theory of types. The paper shows that the language of constructions is capable to express notions from various mathematical fields in a concise way and therefore it can serve as a background for a powerful system for automated theorem-proving.
