We study the (bigraded) homology of the universal Steenrod algebra Q over the prime field F2, and we compute the groups Hs,s(Q), s≥0, using some ideas and techniques of Koszul algebras developed by S. Priddy, although we presently do not know whether or not Q is a Koszul algebra. We also provide an explicit formula for the coalgebra structure of the diagonal homology D∗(Q)=⨁s≥0Hs,s(Q) and show that D∗(Q) is isomorphic to the coalgebra of invariants Γ introduced by W. Singer.

Abstract: | We study the (bigraded) homology of the universal Steenrod algebra Q over the prime field F2, and... we compute the groups Hs,s(Q), s≥0, using some ideas and techniques of Koszul algebras developed by S. Priddy, although we presently do not know whether or not Q is a Koszul algebra. We also provide an explicit formula for the coalgebra structure of the diagonal homology D∗(Q)=⨁s≥0Hs,s(Q) and show that D∗(Q) is isomorphic to the coalgebra of invariants Γ introduced by W.
