On the secondary Steenrod algebra

Date: Nov 2010

Abstract: We introduce a new model for the secondary Steenrod algebra at the prime 2 which is both smaller and more accessible than the original construction of H.-J. Baues. We also explain how BP can be used to define a variant of the secondary Steenrod algebra at odd primes.

Abstract: My PhD thesis. It develops an improved method for the computation of the minimal resolution of the Steenrod algebra. The algorithm is based on some well-known vanishing theorems for the cohomology of its sub Hopf algebras.

Abstract: We show how the non-commutativity of P(n) for p=2 leads to complications in the algebra of cooperations P(n)*P(n).
