Every K(n)-local spectrum is the homotopy fixed points of its Morava module


الملخص بالإنكليزية

Let n geq 1 and let p be any prime. Also, let E_n be the Lubin-Tate spectrum, G_n the extended Morava stabilizer group, and K(n) the nth Morava K-theory spectrum. Then work of Devinatz and Hopkins and some results due to Behrens and the first author of this note, show that if X is a finite spectrum, then the localization L_{K(n)}(X) is equivalent to the homotopy fixed point spectrum (L_{K(n)}(E_n wedge X))^{hG_n}, which is formed with respect to the continuous action of G_n on L_{K(n)}(E_n wedge X). In this note, we show that this equivalence holds for any (S-cofibrant) spectrum X. Also, we show that for all such X, the strongly convergent Adams-type spectral sequence abutting to pi_ast(L_{K(n)}(X)) is isomorphic to the descent spectral sequence that abuts to pi_ast((L_{K(n)}(E_n wedge X))^{hG_n}).
