Spectral galois theory
WebIn this paper a Galois theory of spectral curves is given that classifies the spectral curves from an integrable system. The spectral curves correspond to conjugacy classes of … Webspectral sequences for mod n etale´ K-theory, including a spectral sequence of Galois descent type for the mod n etale´ K-theory of S which starts with Galois cohomology of the Grothendieck fundamental group of S, with coefficients in etale´ K-groups. We shall also discuss some standard comparisons with other flavours of K-theory.
