Milnor operations and classifying spaces

Algebraic Topology 2026-01-13 v2

Abstract

We give an example of a nonzero odd degree element of the classifying space of a connected Lie group such that all higher Milnor operations vanish on it. It is a counterexample for a conjecture of Kono and Yagita.
