The relational model is injective for Multiplicative Exponential Linear Logic (without weakenings)
We show that for Multiplicative Exponential Linear Logic (without weakenings) the syntactical equivalence relation on proofs induced by cut-elimination coincides with the semantic ...

On Completeness of Logical Relations for Monadic Types
Interesting properties of programs can be expressed using contextual equivalence. The latter is difficult to prove directly, hence (pre-)logical relations are often used as a tool ...

What's in a code? Towards a Formal Account of the Relation of Ontologies and Coding Systems
Terminologies are increasingly based on “ontologies” developed in description logics and related languages such as the new Web Ontology Language, OWL. The use of description l...

Qualitative Logics and Equivalences for Probabilistic Systems
We investigate logics and equivalence relations that capture the qualitative behavior of Markov Decision Processes (MDPs). We present Qualitative Randomized Ctl (Qrctl): formulas o...

Formalising in Nominal Isabelle Crary's Completeness Proof for Equivalence Checking
In the book on Advanced Topics in Types and Programming Languages, Crary illustrates the reasoning technique of logical relations in a case study about equivalence checking. He pr...
