An MU-analogue of the lambda algebra (Q1822093)

This paper constructs a differential graded algebra \(\Lambda^{MU}\) in MU-cohomology theory analogous to the lambda algebra in ordinary cohomology theory. The cohomology of the resulting cochain complex \(H^{s,t}(\Lambda^{MU},d)\) is isomorphic to \(Ext^{s,t}_{MU*MU}(MU_*,MU_*)\) and there is a spectral sequence of Adams-Novikov type for which the \(E_ 1\)-term is \(\Lambda^{MU}\).
