متن کاملMath 527 - Homotopy Theory Additional notes
The collection of k-closed subsets of X forms a topology, which contains the original topology of X (i.e. closed subsets are always k-closed). Notation 1.2. Let kX denote the space whose underlying set is that of X, but equipped with the topology of k-closed subsets of X. Because the k-topology contains the original topology on X, the identity function id : kX → X is continuous. Definition 1.3....
متن کاملMath 527 - Homotopy Theory Cofiber sequences
The notion of cofiber sequence is dual to that of fiber sequence. Most constructions and statements about fiber sequences readily dualize to cofiber sequences, though there are differences to be mindful of. 1. Fiber sequences were defined in the category of pointed spaces Top * , so that taking the strict fiber (i.e. preimage of the basepoint) makes sense. No such restriction exists for cofiber...
متن کاملMath 527 - Homotopy Theory Hurewicz theorem
Alternate proof. Using a bit of differential topology (or a more geometric construction along the lines of Hatcher § 4.1 Exercise 15), consider the degree of a smooth map f : S → S. Since every homotopy class [f ] contains a smooth representative, and all such maps have the same degree (i.e. degree is a homotopy invariant), this defines a function deg : πn(S )→ Z. One readily shows that deg is ...
متن کاملSmooth varieties up to A -homotopy and algebraic h-cobordisms
We start to study the problem of classifying smooth proper varieties over a field k from the standpoint of A-homotopy theory. Motivated by the topological theory of surgery, we discuss the problem of classifying up to isomorphism all smooth proper varieties having a specified A-homotopy type. Arithmetic considerations involving the sheaf of A-connected components lead us to introduce several di...
