Homogeneous Functions and Algebraic K--theory
R. Keith Dennis, Reinhard C. Laubenbacher
In this paper we develop the theory of homogeneous functions between finite abelian groups. Here, a function f:G⟶H between finite abelian groups is homogeneous of degree d if f(nx)=ndf(x) for all x∈G and all n which are relatively prime to the order of x. We show that the group of homogeneous functions of degree one from a group G of odd order to ℚ/ℤ maps onto SK1(ℤ[G]), generalizing a result of R. Oliver for p-groups.
