The goal of this project is the development of mathematical structures for programming semantics in Homotopy Type Theory (HoTT), crucially employing higher inductive types and HoTT’s characteristic view of types as geometric spaces. The project will mainly study the denotational semantics of programming languages with support for nondeterministic/concurrent behaviour, such as process calculi and transition-based systems. Geometric models of concurrency in the style of Fajstrup, van Glabbeek, Goubault, Mimram et al. will also be investigated. The results will be formalized in proof assistants with support for Homotopy Type Theory, such as Cubical Agda.
