The underlying formal language of Coq is a Calculus of Constructions with Inductive Definitions. It is presented in this chapter. For Coq version V7, this Calculus was known as the Calculus of (Co)Inductive Constructions (Cic in short). The underlying calculus of Coq version V8.0 and up is a weaker calculus where the sort Set satisfies predicative rules. We call this calculus the Predicative Calculus of (Co)Inductive Constructions (pCic in short). In Section 4.7 we give the extra-rules for Cic. A compiling option of Coq allows to type-check theories in this extended system.

In pCic  all objects have a type. There are types for functions (or programs), there are atomic types (especially datatypes)... but also types for proofs and types for the types themselves. Especially, any object handled in the formalism must belong to a type. For instance, the statement “for all x, P” is not allowed in type theory; you must say instead: “for all x belonging to T, P”. The expression “x belonging to T” is written “x:T”. One also says: “x has type T”. The terms of pCic are detailed in Section 4.1.

In pCic  there is an internal reduction mechanism. In particular, it allows to decide if two programs are intentionally equal (one says convertible). Convertibility is presented in section 4.3.

The remaining sections are concerned with the type-checking of terms. The beginner can skip them.

The reader seeking a background on the Calculus of Inductive Constructions may read several papers. Giménez and Castéran [68] provide an introduction to inductive and coinductive definitions in Coq. In their book [14], Bertot and Castéran give a precise description of the pCic based on numerous practical examples. Barras [9], Werner [136] and Paulin-Mohring [118] are the most recent theses dealing with Inductive Definitions. Coquand-Huet [29, 30, 31] introduces the Calculus of Constructions. Coquand-Paulin [32] extended this calculus to inductive definitions.
