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.
Claims about whether a mathematical statement said to be from Erdős's open-problem corpus was actually posed by Erdős himself, or is instead a variant, restatement, or catalog entry not due to Erdős (e.g. via erdosproblems.com or other catalogs). Covers counting and classifying solved statements by provenance; excludes claims about the truth of the statements themselves.
Nothing matches these filters. Try widening the importance band, the assessment filter or the kind.
