Workshop on inductive definitions

An inductively defined domain is a domain whose elements may be thought of as having been generated in a stepwise fashion. Standard examples are the natural numbers, the words over some alphabet, and the constructive ordinals. Over an inductively defined domain, functions may be defined by induction on the structure of the elements. Both forms of inductive definition are central to mathematics. In constructive mathematics, in particular, they are usually treated as primitive forms of definition. In this workshop, both conceptual and technical aspects of inductive definitions will be discussed.
