Weak omega-categories are a very challenging concept to study rigorously in mathematics, as the axioms defining them are very intricate and complicated to verify. In this talk I will present a way of dealing with this complexity algorithmically, by designing a language relying on dependent type theory. This language allows for the implementation of an interactive theorem prover “CaTT” dedicated to work with weak omega-category. I will then present the semantics of this language and formally relate its models with anterior notions of weak omega-categories, which is the main contribution of my PhD thesis.
