Recursive type generativity
Existential types provide a simple and elegant foundation for uning generative abstract data types, of the kind supported by the Standard ML module system. However, in attempting ...

Checking Emptiness of Non-Deterministic Regular Types with Set Operators
An algorithm to decide the emptiness of a regular type expression with set operators given a set of parameterized type definitions is presented. The algorithm generalizes previous...

Feasible functionals and intersection of ramified types
We show that the basic feasible functions of Cook and Urquhart's BFF [8,9] are precisely the functionals definable in a natural system of ramified recurrence that uses type i...
