This lecture presents examples of cell decomposition, discussing points at which cell decomposition occurs, like a cell in a plan projective. It covers various instances of cell decomposition and their applications in different models, such as the circle addressing other cellular models. The lecture also delves into the compatibility of cell decomposition with different models and the concept of homeomorphism. Furthermore, it explores the equator of different structures and the application of degree 2 pushouts in cellular decomposition.
