There is a series of four fundamental and long-standing conjectures on group rings attributed to Kaplansky. For example, the zero divisor conjecture states that the group ring of a torsion-free group with field coefficients has no zero divisors. I will discuss these conjectures, their connections to other open questions in various areas of mathematics (such as soficity), and the disproof of the unit conjecture.
