Satisfiability and group rings
Group rings are key objects in many fields of mathematics including algebra, topology, operator algebras and representation theory. Fundamental questions about them remain unanswered, in particular several conjectures attributed to Kaplansky. For torsion-free groups and field coefficients, the zero divisor conjecture predicts the absence of zero divisors and the idempotent conjecture predicts that 0 and 1 are the only idempotents in the group ring. The direct finiteness conjecture says that left-invertible elements are invertible in group rings of arbitrary groups over fields. These conjectures have a history spanning more than 80 years. Although special cases are known, resolving any of…
