Embedding group algebras into finite von Neumann regular rings
arXiv:0708.2243
Abstract
Let G be a group and let K be a field of characteristic zero. We shall prove that KG can be embedded into a von Neumann unit-regular ring. In the course of the proof, we shall obtain a result relevant to the Atiyah conjecture.
