A short geometric derivation of the dual Steenrod algebra

Algebraic Topology 2021-09-08 v2

Abstract

This two-page note gives a non-computational derivation of the dual Steenrod algebra as the automorphisms of the formal additive group. Instead of relying on computational tools like spectral sequences and Steenrod operations, the argument uses a few simple universal properties of certain cohomology theories.
