## The Nonzero K-Theory of Finite Rings is Finite

Let \(R\) be a finite ring. The example we'll have in mind at the end is the ring of \(2\times 2\) matrices over a finite field, and subrings. A. Kuku proved that \(K_i(R)\) for \(i\geq 1\) are finite abelian groups. Here, \(K_i(R)\) denotes Quillen's \(i\)th \(K\)-group of the ring \(R\). In this post we will […]
