In this paper, we introduce a common semantic framework for developing and formally modeling use cases and task models. Use cases are the notation of choice for functional require...
We study the relation between Nominal Logic and the Theory of Contexts, two approaches for specifying and reasoning about datatypes with binders. We consider a natural-deduction s...
To fix the semantics of different kinds of parthood relations we require axioms which go beyond those characterizing partial orderings. I formulate such axioms and show their impl...
