Overview
Our work concerns the development and study of precise mathematical formalisms that can be employed for the design, specification, and verification of computer programs. This is in a tradition of mathematical semantics that was started in the UK in the 1960s by Peter Landin, Christopher Strachey, and Dana Scott. This kind of semantics encompasses many mathematical theories, foremost among them order theory, topology, logic, game theory, and category theory, all of which feature in the work of the Birmingham Theory Group. The rich and often surprising interplay between these mathematical areas and programming concerns gives rise to wonderful opportunities for deep and conceptual research.
