Curtis’s conjecture
What the paper claims, in its own words
Proves Curtis’s conjecture: the positive-degree mod-two stable Hurewicz image of the sphere is spanned by the images of the Hopf-invariant-one classes η, ν, σ and the Kervaire-invariant-one classes that exist.
The plain-language explainer for this entry is still coming.
