Candidate status

Unadjudicated candidate

Unadjudicated

The Register publishes this census record without endorsing or adjudicating the mathematical claim.

Unadjudicated does not mean endorsed.

A refutation is recorded in the census evidence below. This records a public response, correction, or withdrawal; it is not a Register adjudication.

Register census note

Inclusion basis

The title addresses the problem directly and the abstract claims P is properly contained in NP.

Links recorded by the census

The same link-list treatment is used across both corpora. These 63 post-2016 URLs carry the census’s dated link state; the 45-of-174 link-rot statistic remains explicitly historical.
