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

Time   12:00

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.
