Methodology

An author must have at least 2 distinct published papers with Primary MSC 42 and at least 3 distinct published papers with MSC 42 anywhere. The first two count toward the three. Multiple MSC 42 codes on one paper do not create additional papers. Primary MSC 42 is verified against the zbMATH cc:*42 search set. Books and unpublished preprints do not count toward eligibility.

Once an author qualifies, the score includes their historical papers across all mathematical fields, without an MSC 42 filter. Author identity follows zbMATH author identifiers; nationality is not inferred from names.

P = 10 × (3E + MB + B/3 + R/9). E, MB, B and R count verified papers in each journal grade. No coauthor division, time decay or field discount is applied. The lifetime scope does not apply the funding application limit of ten papers or its application-year window.

Ranking uses the integer U = 27E + 9MB + 3B + R and displays P = 10U/9, an exact implementation of the same formula. Ties share a rank; names provide a stable order within ties.

The site uses a fixed edition of the ANID journal list. Renamed journals and aliases are merged only through explicit mappings. Unlisted journals are not automatically assigned grade R. Papers without sufficient evidence for a grade are marked unverified and are not included in the verified score. Where unverified papers remain, the displayed score is incomplete. Preprints receive no journal score; explicit exclusions are recorded separately.

The first run imports the full corpus. Weekly updates then import new and revised records, reassess eligibility and build a complete ranking snapshot. A validated snapshot replaces the public ranking automatically. Failed updates retain the last successful result; the page reports the actual data cutoff.
