<p>Does anyone know of a reference in which homotopy coinvariants of some coaction in the category of spectra are explicitly calculated? Particularly in the case of Hopf-Galois extensions of ring spectra. </p> <p>Thanks!</p> <p>-----(EDIT)------ I should mention that I later realized the above concept is not in John Rognes' monograph. It is in Kathryn Hess' paper on homotopical Hopf-Galois extensions and Fridolin Roth's recent dissertation. My apologies to anyone who went looking in Rognes' paper. </p>
