Some Properties of Fox Torus Homotopy Groups
In 1945, R. Fox introduced the so-called Fox torus homotopy groups in which the usual homotopy groups are embedded and their Whitehead products are expressed as commutators. A modern treatment of Fox torus homotopy groups and their generalization were given by the authors in an earlier work. In this note, we further explore these groups and their properties. We discuss co-multiplications on Fox...
متن کاملA Torus Theorem for Homotopy Nilpotent Groups
Nilpotency for discrete groups can be defined in terms of central extensions. In this paper, the analogous definition for spaces is stated in terms of principal fibrations having infinite loop spaces as fibers, yielding a new invariant we compare with classical cocategory, but also with the more recent notion of homotopy nilpotency introduced by Biedermann and Dwyer. This allows us to character...
متن کاملClassification of Homotopy Torus Knot Spaces
The existence of nontrivial homotopy torus knot spaces is established as a corollary to the Theorem. Let p and q be two integers with p > 1, q > 1, and (p, q) = 1. Let % be a maximal set of topologie ally distinct compact orientable irreducible 3-mainfolds with fundamental group presented by (a, b\apb'i). Then card (%) = '/2*(pg), where ♦ denotes Euler's function. All spaces are piecewise linea...
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...
متن کاملHomotopy Nilpotent Groups
We study the connection between the Goodwillie tower of the identity and the lower central series of the loop group on connected spaces. We define the simplicial theory of homotopy n-nilpotent groups. This notion interpolates between infinite loop spaces and loop spaces. We prove that the set-valued algebraic theory obtained by applying π0 is the theory of ordinary n-nilpotent groups and that t...
