A note on the second James-Hopf invariant

Summary · qwen2.5:32b

The paper characterizes the stabilized second James-Hopf invariant through three defining axioms, notably its adherence to the Cartan formula and its vanishing property on suspensions. This work advances understanding in algebraic topology by uniquely specifying this invariant via natural transformations, utilizing a combination of the natural stable splitting of the James construction and Goodwillie calculus in its proof.

arXiv:2606.29486v2 Announce Type: replace Abstract: This paper characterizes the stabilized second James-Hopf invariant by means of three axioms. Specifically, we show that it is the unique natural transformation satisfying the Cartan formula, vanishing on suspensions. The proof combines the natural stable splitting of the James construction with Goodwillie calculus.
