  • This talk lays the foundation for the next 2-3 talks. We discuss the problem ofembedding group rings into skew fields. We discuss the notion of Ore localizationand how to embed group rings of torsion-free amenable groups into skewfields.Why is the problem more difficult in the non-amenable case? What is Linnell’sring.
