Dynamic typing can be useful in statically typed languages. We extend the simply typed λ-calculus with dynamic typing and elaborate additional features like polymorphism and subty...
This paper extends the idea of co-types (described in a companion paper) to include the concept of adjustment hierarchies. An adjustment hierarchy provides a parallel hierarchy to...

In this paper we solve an open problem posed in our previous work on asynchronous subtyping [12], extending the method to higher-order session communication and functions. Our syst...
An important relation in information extraction is the part-whole relation. Ontological studies mention several types of this relation. In this paper, we show that the traditional...
O'Haskell is a programming language derived from Haskell by the addition of concurrent reactive objects and subtyping. Because Haskell already encompasses an advanced type sy...
