DESCRIPTION:Kaplansky made various related conjectures about group rings\,
  especially for torsion-free groups. For example\, the zero divisor conjec
 ture predicts that if K is a field and G is a torsion-free group\, then th
 e group ring K[G] has no zero divisors. I will survey what is known about 
 the conjectures\, including their relationships to each other and to other
  group properties such as orderability\, and present some recent progress.
