Claims
Search the graph by meaning. Each result carries its current verdict; open one to see its decomposition, provenance, and the reasoning behind the assessment.
Schemes equipped with group structure: finite flat group schemes, Cartier duality, p-divisible (Barsotti–Tate) groups, and classification results such as Oort–Tate. Claims about their structure, order, duality, or morphisms belong here; abstract group theory without scheme structure does not.

If a claim here is wrong, or missing evidence, open it: every claim page carries its own entry for challenges, evidence, and corrections. If the graph is missing a claim entirely, propose it below. A proposal is reviewed on its merits; accepted claims are matched against the graph and enter it with their reasoning on record.
