On the toplogical computation of K4 of the Gaussian and Eisenstein integers

Mathieu Dutour Sikiric, Herbert Gangl, Paul E. Gunnells +3

In this paper we use topological tools to investigate the structure of the algebraic K-groups K_4 (Z[i]) and K_4 (Z[rho]), where i := sqrt{-1} and rho := (1+sqrt{-3})/2. We exploit…
