Rational Morava \(E\)-theory and \(DS^ 0\)
The extended-power spectrum \(DS^0\) has two coproducts and two products, which interact in an intricate way. Given an \(H_\infty\) ring spectrum \(E\), the resulting algebraic structure on \(E^*DS^0\) gives a framework in which to encode information about power operations. In this paper we use the character theory of Hopkins, Kuhn and Ravenel to describe \(E^*DS^0\) for certain interesting cohomology theories. We will not, however, discuss power operations in the present work.
