Mathematical Genealogy

Close relations of the Top 100, by proximity score

Every PhD mathematician has an advisor, and every advisor has an advisor. The Mathematics Genealogy Project catalogs this lineage. We use it to surface close relations: researchers not in the Top 100 by publication count, but who sit in its immediate orbit through advisor-student relationships.

How the proximity score works

We build one graph from the advisor and student trees of all Top 100 researchers. A close relation is an outsider directly tied (as advisor or student) to at least two Top 100 researchers. Each gets a proximity score that sums, over those direct ties, 101 minus the connected researcher's rank. Being tied to the top of the list counts for much more than being tied to the bottom. Only direct ties count; people already in the directory and deceased mathematicians are excluded.

What this crawl covered

We crawled the advisor and student trees of the 76 Top 100 researchers who have an entry in the Mathematics Genealogy Project, and every node in those trees was fetched. The remaining 24 of the 100 have no entry in that database, so their lineage cannot be traced and this page cannot speak for them.
