WebJan 17, 2024 · Remark. The usage of the 𝔸 1 \mathbb{A}^1 - prefix in the above definitions may seem strange since all these notions are simply inherited from the Nisnevich (∞,1)-topos. The point is that, when a smooth scheme X X is viewed as a motivic space, a localization functor is implicitly applied. The underlying Nisnevich (∞,1)-sheaf of the … Web2 HOMOTOPY AND PATH HOMOTOPY { Operations on homotopy classes of maps. The nice point to consider the space of maps (and the space of homotopy classes of maps)[instead of to study the topological spaces themselves]is that one has many natural operations on the space of maps. For example, here are some natural operations on homotopy classes …
