Exact Squares | The n-Category Café - University of Texas at Austin
WEBJun 21, 2010 · In order to get used to the calculus of exact squares, the first thing we have to change is to start thinking more in terms of Kan extensions rather than limits and colimits.For instance, it’s usual to think of a pullback as the limit of a diagram of shape B → C ← A B \to C \leftarrow A (a cospan) i.e. an object P P equipped with a natural transformation of cospans: P → P ← P ↓ ↓ ...
Semi-Simplicial Types, Part I: Motivation and History
WEBMar 9, 2024 · A semi-simplicial set is defined to consist of sets Xn for n ≥ 0, along with face maps ∂k: Xn → Xn − 1, for k ∈ {0, …, n}, satisfying the relations: ∂k ∘ ∂l = ∂l − 1 ∘ ∂k for k <l. One thinks of Xn as the set of n -simplices, and of the face maps as giving the boundary components of a given n -simplex. For example, X0 ...
