System F-sub
From HandWiki
Short description: Typed lambda calculus
In the branch of mathematical logic known as type theory, System F<:, pronounced "F-sub", is an extension of system F with subtyping. System F<: has been of central importance to programming language theory since the 1980s[citation needed] because the core of functional programming languages, like those in the ML family, support both parametric polymorphism and record subtyping, which can be expressed in System F<:.
