Termination checking with types
Journal article, 2004

The paradigm of type-based termination is explored for functional programming with recursive data types. The article introduces Lambda(mu)(+), a lambda-calculus with recursion, inductive types, subtyping and bounded quanti. cation. Decorated type variables representing approximations of inductive types are used to track the size of function arguments and return values. The system is shown to be type safe and strongly normalizing. The main novelty is a bidirectional type checking algorithm whose soundness is established formally.
