EnglishWe apply the methodology of domain refinement to systematically derive domains for type analysis. Domains are built by iterative application of the Heyting completion operator to a given set of basic types. We give a condition on the type system which assures that two steps of iteration are sufficient to reach the fixpoint. Moreover, we provide a general representation for type domains through transfinite formulas. Finally, we show a subset of finite formulas which can be used as a computationally feasible implementation of the domains and we define the corresponding abstract operators.

| Abstract: | We apply the methodology of domain refinement to systematically derive domains for type analysis. Domains are built by iterative application of the Heyting completion operator to a given set of basic types. We give a condition on the type system which assures that two steps of iteration are sufficient to reach the fixpoint. Moreover, we provide a general representation for type domains through transfinite formulas. Finally, we show a subset of finite formulas which can be used as a computationally feasible implementation of the domains and we define the corresponding abstract operators. |
