Web24. nov 2024 · The syntax of refinement types is given by the following grammar: The occurrence of x in {x} \mathbin {:}\mathbf {Int} \rightarrow \tau is a binding occurrence. We shall not distinguish between \alpha -equivalent refinement types. Each refinement type \tau describes a property on formulas and semantic elements of a simple type \rho . Web17. feb 2014 · A refinement type is a type together with a decidable predicate: { x: T p ( x) } where x is a variable name, T is a type, and p ( x) is a decidable predicate over x. A dependent pair type is the product type of two types where the second type depends on the value of the first: ( x: T) × q ( x)
