Who's Who in Conjecture Research: ranked researcher directories for seven number-theory problems

Ranked directories of researchers active on seven open problems in number theory (Goldbach, Riemann, twin primes, abc, Legendre, n^2+1, and Landau's problems). Each researcher is ranked by a three-source composite over arXiv, OpenAlex, and zbMATH merged with a weighted order statistic; per-source ranks, provenance, institution, country, and active years are included.
