Mechanized metatheory for a $$\lambda $$ λ -calculus with trust types

Rodrigo Ribeiro, Lucília Figueiredo, Carlos Camarão
2013 Journal of the Brazilian Computer Society  
In this work, we use the Coq proof assistant to formalise a λ-calculus with trust types, originally formulated by Ørbaek and Palsberg.  ...  We give formal proofs of type soundness, erasure and simulation theorems and also prove decidability of the typing problem. As a result of our formalisation a certified type checker is derived.  ...  The formalisation of a unification algorithm has been studied elsewhere [26, 32] . We let a formalisation of the type inference problem for this trust-calculus for future work.  ...

Nominal Terms and Nominal Logics: From Foundations to Meta-mathematics [chapter]

Murdoch J. Gabbay
2013 Handbook of Philosophical Logic  
This is possible because of a novel name-carrying semantics in nominal sets, through which our languages will have name-permutations and term-formers that can bind as primitive built-in features.  ...  and completeness; various axiomatisations with pointers to proofs of their correctness; and we conclude with a case study stating and proving correct a finite first-order axiomatisation of arithmetic  ...  Fernández and the author introduced a notion of closed term such that for closed terms, equivariant matching/unification coincides with 'ordinary' matching/unification [FG07] .  ...

A symbolic framework for multi-faceted security protocol analysis

2007 International Journal of Information Security  
, formal, so as to be provably correct, and with a computational counterpart, so as to support the (semi-) automated certification of properties.  ...  It features a clear separation between the modeling of the protocol functioning and the properties it is expected to enforce, the former in terms of a calculus, the latter in terms of a logic.  ...  SPL has many similarities with cIP, for instance input prefixes embed a pattern matching mechanism such that variables are instantiated when a matching message is received.  ...

GONE WITH THE EURO: A REAPPRAISAL OF THE PESETA'S ADJUSTMENT MECHANISM (1870-1998)

José María Serrano, María Dolores Gadea, Marcela Sabaté
2017 Revista de Historia Económica / Journal of Iberian and Latin American Economic History  
This paper presents a chronology of the moments when the adjustment was crucial, which, consistent with the macro-trilemma, coincided with periods of external openness.  ...  Moreover, this paper provides empirical support to the thesis that links the exceptionality of a floating peseta during the gold standard with fiscal profligacy.  ...  We formalise this trade-off between integration and the speed of exchange rates reverting to equilibrium through a non-parametric approach and find a systematic negative relationship between the Spanish  ...

When Eastern Labour Markets Enter Western Europe: CEECs Labour Market Institutions Upon Euro Zone Accession

Joanna Tyrowicz
2009 Social Science Research Network  
Traditionally, labour markets are a key concept in the optimal currency area theory, playing the role of the only accommodation mechanism of asymmetric shocks after the monetary unification.  ...  Many empirical studies addressed these issues too, yielding important policy implications for labour market reforms in the process of monetary unification.  ...  Indeed, such a long perspective combined with the little experience Europe has with common currency should suggest humbleness in 37 See Halko (2003) for a formalised theoretical model, calibrated simulation  ...

2018 EFSA Journal  
Following a request from EFSA, the Panel on Plant Protection Products and their Residues (PPR) developed an opinion on the state of the art of Toxicokinetic/Toxicodynamic (TKTD) models and their use in  ...  TKTD models are species- and compound-specific and can be used to predict (sub)lethal effects of pesticides under untested (time-variable) exposure conditions.  ...  For what concerns the calibration data, the actual profile in the study matched the nominal concentrations reasonably well (mean measured concentrations between 95% and 112% of the nominal).  ...

Resolving Relative Time Expressions in Dutch Text with Constraint Handling Rules [chapter]

Matje van de Camp, Henning Christiansen
2013 Lecture Notes in Computer Science  
We discuss the semantics of NL coordination in modern type theories (MTTs) with coercive subtyping. The issue of conjoinable types is handled by means of a type universe of linguistic types.  ...  This is achieved without requiring annotation at the level of individual words, via a method compatible with work on linguistic change and routinisation. Abstract.  ...  Acknowledgments This work was partly funded by a JAE Predoctoral Fellowship from CSIC (Spain).  ...
