Mathematical Abstraction, Part 9: Higher Homotopy
Part nine of Mathematical Abstraction asks why demanding exact equality can obscure the structure that matters. Simplices and simplicial sets provide a combinatorial language for spaces, while horns and Kan complexes make higher relationships explicit. Model categories organize homotopy beyond an individual geometric example, and Dold–Kan reveals algebra inside these constructions. The episode assembles the foundations needed to discuss higher structure and prepares the final ascent of the series.
