OpenAI's result summary

Proves the weak pinned Erdős distance conjecture: for every fixed ε > 0, all but o(n) points of any n-point planar set determine at least n^{1-ε} distinct nonzero distances. A complementary theorem bounds the number of unit-distance pairs by O(n^{4/3-δ}) for an absolute δ > 0.

MANUSCRIPT 01

The weak pinned planar distance theorem

We prove the weak pinned Erdős distinct-distance conjecture. For every fixed ε > 0, all but o(n) points of any n-point planar set determine at least n^{1-ε} distinct nonzero distances.

MANUSCRIPT 02

A power saving for planar unit distances

We prove a power saving for the planar unit-distance problem: for some absolute β< 4/3, every set of n points in the Euclidean plane determines O(n^β) unordered pairs at unit distance.

One signal in the wider AGI picture

New mathematical reasoning could help AI tackle harder scientific and computational problems. How reliably these skills transfer beyond mathematics will determine how much they contribute to general intelligence.
