Homotopy Classes of Maps between Knaster Continua
For each positive integer n, let gn : I → I be defined by the formula gn (t) = v (nt). Observe that gn stretches n times and then folds the resulting interval [0, n] onto [0, 1]. The map g2 is the very well known “roof-top” map. For any two positive integers m and n, gm ◦ gn = gmn. Consequently, gn and gm commute (see, for example, [8, Proposition 2.2]). Let N = {n1, n2, . . . } be a sequence o...
متن کاملRealizing Kasparovs Kk-theory Groups as the Homotopy Classes of Maps of a Quillen Model Category
In this article we build a model category structure on the category of sequentially complete l.m.c.-C*-algebras such that the corresponding homotopy classes of maps Ho(A,B) for separable C*-algebras A and B coincide with the Kasparov groups KK(A,B).
متن کاملHomotopy Variation Map and Higher Homotopy Groups of Pencils
We prove in a synthetic manner a general Zariski-van Kampen type theorem for higher homotopy groups of pencils on singular complex spaces.
متن کاملOn the homotopy groups of spheres in homotopy type theory
The goal of this thesis is to prove that π4(S) ' Z/2Z in homotopy type theory. In particular it is a constructive and purely homotopy-theoretic proof. We first recall the basic concepts of homotopy type theory, and we prove some well-known results about the homotopy groups of spheres: the computation of the homotopy groups of the circle, the triviality of those of the form πk(S) with k < n, and...
متن کاملExtraordinary Homotopy Groups
In this talk, we’ll introduce the field of chromatic homotopy theory, which is where all the major advancements on the πS ∗ problem have come from in the past 30+ years. Our express goal will be to study the Picard groups of the K(n)-localized stable categories, but to even make sense of that we’ll have to go on a fairly deep safari through chromatic homotopy. Technical aspects will be mostly k...
