Source and edition

Jiří Lebl, Guide to Cultivating Complex Analysis: Working the Complex Field, version 1.9 (11 July 2026), Laurent series.

This modified teaching unit adapts the one-variable theorem and its two-circle proof. It is distributed under CC BY-SA 4.0, selected from the author’s dual grant. These terms apply to the entire unit, not CC0.

GPT-6 Astra (OpenAI), in Codex at Ultra, supplied the quantitative product estimates, coordinate-extension proofs, homogeneous complex, illustration and solved exercises, and self-checked the unit. No independent AI or human review is claimed.

Author’s complete editable source · Unmodified selected LaTeX passage · Author’s supplied terms · Editable teaching unit · Read the unit.

The selected raw LaTeX passage uses the original book’s macros and figure assets; the complete author source supplies them. It is not a standalone compilable document. The teaching unit and its SVG illustration are independently readable here.

An edition omitting share-alike components must keep the source credit and explicitly mark the missing prerequisite proof. A fallback citation alone does not supply that proof.
