Abstract

In this paper we study the K-theory of the integral group ring Ζ[C4×C4]. We prove that the relative SK1 group of the integral group ring Ζ[C4×C4] is an elementary Abelian group of rank-3. We also show that the 4-rank of K2(Ζ[C4×C4]) is at least 1 and the 2-rank of K2(Ζ[C4×C4]) is at least 10.
