Explicit substitution on the edge of strong normalization
1999
Theoretical Computer Science
We use the recursive path ordering (RPO) technique of semantic labelling to show the preservation of strong normalization (PSN) property for several calculi of explicit substitution. ...
PSN states that if a term M is strongly normalizing under ordinary p-reduction (using 'global' substitutions), then it is strongly normalizing if the substitution is made explicit ('local'). ...
Acknowledgements Thanks to Thomas Arts for making us aware of current notations for the recursive path orders, using semantic labelling. ...

We present here some usual results on substitution calculi [5] . Lemma 6 (Strong normalization of x). x is strongly normalizing and its normal forms are pure objects (i.e. without substitutions). ...

Simple Proofs of Characterizing Strong Normalization for Explicit Substitution Calculi
[chapter]
Lecture Notes in Computer Science
We present a method of lifting to explicit substitution calculi some characterizations of the strongly normalizing terms of λ-calculus by means of intersection type systems. ...
Then we present a new intersection type system in the style of sequent calculus, and show that it characterizes the strongly normalizing terms of Dyckhoff and Urban's extension of Herbelin's explicit substitution ...

Strong normalization of explicit substitutions via cut elimination in proof nets
Proceedings of Twelfth Annual IEEE Symposium on Logic in Computer Science
in the field of explicit substitutions. ...
This correspondence allows us to prove that a typed version of the λx-calculus [34, 5] is strongly normalizing, as well as of all the calculi that can be translated to it keeping normalization properties ...
Strong normalization of the calculus of explicit substitutions alone, called the σ-calculus, is proved in [8] , but the σ-calculus together with the Beta rule does not preserve β-strong normalization ...

Explicit Substitutions and Reducibility
2001
Journal of Logic and Computation
To illustrate this point, we give a proof of strong normalization (SN) for simply-typed call-by-name -calculus enriched with operators of explicit unary substitutions. ...
We consider reducibility sets defined not by induction on types but by induction on sequents as a tool to prove strong normalization of systems with explicit substitution. ...
Strong normalization proofs The traditional approach to strong normalization (SN) in -calculi with explicit substitution is through the property of preservation of strong normalization (PSN). ...

Evolution of transport properties of BaFe2−xRuxAs2in a wide range of isovalent Ru substitution
2012
Physical Review B
The effects of isovalent Ru substitution at the Fe sites of BaFe2-xRuxAs2 are investigated by measuring resistivity and Hall coefficient on high-quality single crystals in a wide range of doping (0 < x ...
Ru substitution weakens the antiferromagnetic (AFM) order, inducing superconductivity for relatively high doping level of 0.4 < x < 0.9. ...
Having established the phase diagram of BaFe 2−x Ru x As 2 , we discuss the effects of Ru substitution on the normal state electrical transport properties for a wide range of x. ...

One important application of uniform normalization is in prov- ing strong normalization in systems of type assignment, since it is often easier to prove that weak normalization holds than to prove strong ...

A short proof of the strong normalization of the simply typed λμ-calculus
[article]
2009
arXiv
pre-print
We give an elementary and purely arithmetical proof of the strong normalization of Parigot's simply typed λμ-calculus. ...
This proof is based on a proof of the strong normalization of the simply typed λ-calculus due to the first author (see [2] ) which, itself, is a simplification of the one given by R. ...
The first proof of the the strong normalization of the λµ-calculus for the types of Girard's system F was done by Parigot in [6] in two different ways : by using reducibility candidates and by a CPS ...

COALITION-PROOF NASH EQUILIBRIA IN A NORMAL-FORM GAME AND ITS SUBGAMES
2010
International Game Theory Review
Ray (2001) also established that a strong equilibrium (Aumann, 1959) of a subgame is a strong equilibrium of the original game under the condition of no coalitional benefit. ...
A subgame of a normal-form game is a game in which the strategy sets of all players in the subgame are subsets of those in the normal-form game. ...
In the following, the equilibrium concepts of a normal-form game are introduced. The first is the notion of strong equilibrium introduced by Aumann (1959) . ...

Reductions, intersection types, and explicit substitutions
2003
Mathematical Structures in Computer Science
Given the central place that strong normalization occupies in the theory and application of classical lambda calculus, it is important to study this property in systems of explicit substitutions. ...
The first is to define classes of reduction strategies in the original calculus which support strong normalization; a notable example of work in this area is that of Eike Ritter [34] . ...
Acknowledgements The authors are grateful to Norman Danner, Frédéric Lang, Simona Ronchi della Rocca, and Kristoffer Rose for many helpful discussions and the referees of the conferences LATIN'02 and TCS ...

Extracting a Normalization Algorithm in Isabelle/HOL
[chapter]
2006
Lecture Notes in Computer Science
Unlike many other proofs of weak normalization based on Tait's strong computability predicates, which require a logic supporting strong eliminations and can give rise to dependent types in the extracted ...
We present a formalization of a constructive proof of weak normalization for the simply-typed λ-calculus in the theorem prover Isabelle/HOL, and show how a program can be extracted from it. ...
Although weak normalization follows from strong normalization as a corollary, proofs of weak normalization are interesting in their own right. ...
