Mazur Conjecture on Rational Points


The Mazur conjecture on rational points asserts that, for every algebraic variety V over Q, the topological closure of its rational points V(Q) in its real locus V(R) has only finitely many connected components (Mazur 1995). This finite-components assertion is distinct from Mazur's theorem on elliptic curve torsion subgroups.

A Diophantine set definition of Z in Q would contradict this conjecture (Mazur 1995). Burungale (2026) reports such a definition and the resulting contradiction. This consequence depends on the claimed arithmetic proof, so it is not an independently established refutation.
