Proof Pearl: Abella Formalization of λ-Calculus Cube Property

  • Beniamino Accattoli
Part of the Lecture Notes in Computer Science book series (LNCS, volume 7679)

Abstract

In 1994 Gerard Huet formalized in Coq the cube property of ł-calculus residuals. His development is based on a clever idea, a beautiful inductive definition of residuals. However, in his formalization there is a lot of noise concerning the representation of terms with binders. We re-interpret his work in Abella, a recent proof assistant based on higher-order abstract syntax and provided with a nominal quantifier. By revisiting Huet’s approach and exploiting the features of Abella, we get a strikingly compact and natural development, which makes Huet’s idea really shine.
