Popescu, Andrei; Rosu, Grigore (200505)We show that any institution I satisfying some reasonable conditions can be transformed into another institution, Ib, which captures formally and abstractly the intuitions of adding support for behavioral equivalence and ...

Popescu, Andrei (200903)Combining traces, coalgebra and lazyfiltering channel configurations for parallel composition, we give a fullyabstract denotational semantics for the picalculus under weak early bisimilarity.

Popescu, Andrei; Rosu, Grigore (200607)Generic firstorder logic (GFOL) is a firstorder logic parameterized with terms defined axiomatically (rather than constructively), by requiring them to only provide generic notions of free variable and substitution ...

Popescu, Andrei (20090511)We develop some HigherOrder Abstract Syntax (HOAS) concepts and proof principles as a collection of definitions and propositions on top of the original syntax with bindings. Our approach brings together hasslefree ...

Popescu, Andrei (2010)This collection of documents presents the Isabelle formalization of HigherOrder Abstract Syntax (HOAS) as a definitional layer on top of FirstOrder Abstract Syntax (FOAS). The formal scripts shown here are provided as a ...

Popescu, Andrei; Gunter, Elsa L. (20100128)We present a coinductive proof system for bisimilarity in transition systems specifiable in the de Simone SOS format. Our coinduction is incremental, in that it allows building incrementally an a priori unknown bisimulation, ...

Popescu, Andrei; Serbanuta, Traian Florin; Rosu, Grigore (200505)Interpolation results are investigated for various types of formulae. By shifting the focus from syntactic to semantic interpolation, we generate, prove and classify more than twenty interpolation results for firstorder ...

Popescu, Andrei; Gunter, Elsa L.; Osborn, Christopher J. (2010)We present a point of view concerning HOAS (HigherOrder Abstract Syntax) and an extensive exercise in HOAS along this point of view. The point of view is that HOAS can be soundly and fruitfully regarded as a {\em ...
