# Edition history

## September 2026

The AN-03 course-writing task prepared the independently written *Elliptic Operators & Boundary Problems* draft in OpenAI Codex.

## October 2026

The programme expanded and reorganized the course, preserving its mathematical statements, proofs and source identities. Open Mathematics Courses assembled the boundary-reduction selection and its supporting readings. Exact source editions and component identities are recorded in [the reading manifest](../readings.json).
