Modalities are categorical constructs closely related to weak factorization systems. They play a particularly fundamental role in Homotopy Type Theory, where they are known as “n-truncations.” We will be looking at the notion of modality and truncation from a category-theoretic perspective, and then give some geometric examples in Homotopy Type Theory using Higher Inductive Types. No prior knowledge of algebraic topology and only a basic understanding of category theory is needed. Should be fun!
