The problems of contextual equivalence and approximation are studied for the third-order fragment of Idealized Algol with iteration (IA∗ 3). They are approached via a combination...
We investigate the decidability of observational equivalence and approximation in “Syntactic Control of Interference” (SCI). By asg denotations of terms in an inequationally fu...
We investigate the decidability of observational equivalence and approximation in Reynolds' "Syntactic Control of Interference" (SCI), a prototypical functionalimpe...
The definition of type equivalence is one of the most important design issues for any typed language. In dependentlytyped languages, because terms appear in types, this definition...
We characterize elementary equivalences and inclusions between von Neumann regular real closed rings in terms of their boolean algebras of idempotents, and prove that their theorie...
