[#R1160] Current status and unresolved remainder

claim. UNKNOWN as of 2026-07-31. Abdollahi and Taheri report support size three over \(\mathbb F_2\) as the first unsettled case of Kaplansky's zero-divisor conjecture and prove lower bounds on the support of a partner. Recent work proves the conjecture for further group classes, while the general case remains open in the checked sources. For a positive answer, give a finite or recursive presentation of a torsion-free group \(G\), explicit finite supports and coefficients for nonzero \(\alpha,\beta\in\mathbb F_2[G]\), and verify \(\alpha\beta=0\) in the group algebra.

1Summary

UNKNOWN as of 2026-07-31. Abdollahi and Taheri report support size three over \(\mathbb F_2\) as the first unsettled case of Kaplansky's zero-divisor conjecture and prove lower bounds on the support of a partner. Recent work proves the conjecture for further group classes, while the general case remains open in the checked sources.

A complete resolution must satisfy this condition: For a positive answer, give a finite or recursive presentation of a torsion-free group \(G\), explicit finite supports and coefficients for nonzero \(\alpha,\beta\in\mathbb F_2[G]\), and verify \(\alpha\beta=0\) in the group algebra.
