This Thursday at 12:00, U. Haifa Topology & Geometry seminar on May 30, 2019
Geometry & Topology Seminar
Speaker: David Blanc (University of Haifa)
Topic: The decomposition of unstable homotopy
Place: Room 614 in the Science & Education Building
Date: Thursday, May 30, 2019
In his thesis Joel Cohen showed how the stable homotopy groups of spheres are generated under composition and higher homotopy operations by a few “atomic” elements. We shall show that a similar result holds unstably. For this purpose we will define (unstable) longer Toda brackets, and explain how this notion must be modified to yield the desired result.
Joint work with Samik Basu and Debasis Sen.
