Refinement, what is it? And how do you build your own?

Abstract:
Refinement is defined in a vast number of ways, some definitions are equivalent and some hard to even compare. Worse still the engineering consequences of picking one definition rather than another can be hard to work out. To shed some light on this we give an abstract, parameterized, definition of refinement that has a simple engineering interpretation. Specialising this definition by instantiating the parameters we can build some well known refinements. This allows us to compare and contrast some well known refinement theories. Lastly we make use of theory transformations (Galois connections) to both, make refinement more flexible and,to implement one theory of refinement in another. This provides interesting insights on some well known theories. The talk is largely conceptual and hopefully of interest to the non expert. David will be visiting the PLS group at ITU November 9th-10th, please contact Thomas (hilde@itu.dk) if you want to meet with him.
