Abstract
Let n≥1, p a prime, and T(n) any representative of the Bousfield class of the telescope vn−1F(n) of a finite type n complex. Also, let En be the Lubin-Tate spectrum, K(En) its algebraic K-theory spectrum, and Gn the extended Morava stabilizer group, a profinite group. Motivated by an Ausoni-Rognes conjecture, we show that there are two spectral sequences I\mspace−3muE2s,t⟹πt−s((LT(n+1)K(En))hGn)⟸II\mspace−2muE2s,t with common abutment π∗(−) of the continuous homotopy fixed points of LT(n+1)K(En), where I\mspace−3muE2s,t is continuous cohomology with coefficients in a certain tower of discrete Gn-modules. If the tower satisfies the Mittag-Leffler condition, then there are continuous cochain cohomology groups I\mspace−3muE2∗,∗≅Hcts∗(Gn,π∗(LT(n+1)K(En)))≅II\mspace−2muE2∗,∗. We isolate two hypotheses, the first of which is true when (n,p)=(1,2), that imply (LT(n+1)K(En))hGn≃LT(n+1)K(LK(n)S0). Also, we show that there is a spectral sequence Hctss(Gn,πt(K(En)⊗T(n+1)))⟹πt−s((K(En)⊗T(n+1))hGn).
