Mazur's control theorem, introduced by Barry Mazur in a 1972 paper in Inventiones Mathematicae titled Rational points of abelian varieties with values in towers of number fields, describes the behavior of the Selmer group of an abelian variety over a number field within its Z_p extensions. The Wikipedia article on the theorem is itself a stub, so beyond this core statement its fuller significance within Iwasawa theory is not yet documented in the one source read for this description.

Has Statement Form
Entity-backed identity for the statement-form enum value this theorem already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The statement-form fact itself stays on the theorem unchanged.
