An elementary description of $K_{1} (R)$ without elementary matrices

Thomas Huettemann, Zuhong Zhang

Let $R$ be a ring with unit. Passing to the colimit with respect to the standard inclusions $G L (n, R) \to G L (n + 1, R)$ (which add a unit vector as new last row and column) yields, by…

Triangular objects and systematic K-theory

Thomas Huettemann, Zuhong Zhang

We investigate modules over "systematic" rings. Such rings are "almost graded" and have appeared under various names in the literature; they are special cases of the G-systems of G…

A matrix description for $K_{1}$ of graded rings

Zuhong Zhang

The current paper is dedicated to the study of the classical $K_{1}$ groups of graded rings. Let $A$ be a $Γ$ graded ring with identity $1$ , where the grading $Γ$ is an abelian group…
