lambda-calculus unification · Unification is an algorithmic process of solving equations between symbolic expressions.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We propose related algorithms for unification and constraint simplification in !& , a refinement of the simply-typed -calculus with subtypes and bounded intersection types.

Formally, a unification approach presupposes An infinite set of variables. For higher-order unification, it is convenient to choose disjoint from the set of lambda-term bound variables. A set of terms such that . For first-order unification, is usually the set of first-order terms (terms built from variable and function symbols).

01.03.1988 · Unification delays are formalised independently of any context, by defining a lambda calculus where a unification constraint forms an integral part of each term. This calculus is shown to support an unusually simple unification theory, where most general unifiers trivially always exist.

08.11.2016 · In my understanding, if a unification solves equations of terms that are not higher-order terms, then it is a first-order unification. If a unification solves equations of terms that are higher-order terms, then it is a higher-order unification. Therefore a unification solves equations of $\lambda$-terms should be a higher-order Unification.

Jan 03, 2022 · Unification is an algorithmic process of solving equations between symbolic expressions. I have solved a few execercises in FOL: f (x,b ()) = f (a (),y) has one unifier: [a ()/x,b ()/y], Is it possible to use Unification for Lambda Calculus terms? For example (= means beta reduces to): Equation: (λx.T) b = a b. Solve for T. Solution: [ (a x)/T].

The λ-calculus and combinatory logic are two systems of logic which can also serve as abstract programming languages. They.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. A new unification algorithm is introduced, which (unlike pre-vious algorithms for unification in λ-calculus) shares the pleasant proper-ties of first-order unification. Proofs of these properties are given, in par-ticular uniqueness of the answer and the most-general-unifier property.

In this paper we prove the coherence of a class of lambda-calculus-based languages that use the intersection type discipline, including both a purely functional …

01.06.1975 · A semi-decision algorithm is presented, to search for unification of formulas in typed ω -order λ -calculus, and its correctness is proved. It is shown that the search space is significantly smaller than the one for finding the most general unifiers. In particular, our search is not redundant.
