Mc. Crabb et al., K-THEORY AND THE ANTI-AUTOMORPHISM OF THE STEENROD ALGEBRA, Proceedings of the American Mathematical Society, 124(7), 1996, pp. 2275-2281
We give simple proofs of some relations in the Steenrod algebra involv
ing the powers P-i and their duals P-chi(i) and show how these relatio
ns arise from K-theory.
