Why this site exists

The abc conjecture has been open since 1985. It sits at the intersection of Diophantine approximation, arithmetic geometry, and the theory of heights, and implies a remarkable breadth of consequences in number theory. The community working on it and on the surrounding problems (Szpiro, Vojta, S-unit equations, Thue equations, Belyi maps) is spread across several research areas. This site is a starting point for anyone wanting to know who is active on these topics today, where they are, and what they have been writing.

Who built it

Steve Hubbard built this as a sister project to Who's Who in Goldbach Research and Who's Who in Riemann Hypothesis Research, using the same open pipeline and documented methodology. Suggestions, corrections, and additions are welcome.
