The cohomology of the connective spectra for {K}-theory revisited

Published 12 Jan 2024 in math.KT and math.AT | (2401.06615v2)

Abstract: The stable mod 2 cohomologies of the spectra for connective real and complex K-theories are well known and easy to work with. However, the known bases are in terms of the anti-automorphism of Milnor basis elements. We offer simple bases in terms of admissible sequences of Steenrod operations that come from the Adem relations. In particular, the basis for the complex case is that you don't use any Steenrod operations in degree one or $2n+1$, $n > 0$.
