Full computation of the algebraic K-groups K_n(Z) of the integers

Determine the algebraic K-theory groups K_n(Z) for all degrees n, completing the full computation of the algebraic K-theory of the ring of integers.

Background

In analyzing K(\underline{Z}), the authors observe that K(Z) appears as a retract, which limits the extent of computability for K(\underline{Z}) given the state of knowledge about K(Z).

They explicitly note that the complete determination of K_n(Z) is a longstanding and difficult open problem, which blocks a full computation of the K-groups for \underline{Z}.
