In 3 of the 18 math subfields we track, more than half of arXiv papers by established authors now acknowledge using AI.
Rates have increased rapidly: in differential geometry, the share climbed from ~8% of papers in July to ~57% in September.
AI acknowledgment among established math authors rose sharply, passing half of papers in three of 18 tracked subfields. It shows where AI is becoming routine in research work.
