Family 203. Donovan's conjecture over fields and discrete valuation rings.
The authors are OpenAI. This companion does not verify the proof and does not adopt it as a theorem of Ngo Cheung’s series. It is not a premise. O.1 stays NOT_CLOSED. Anti-de Sitter results are not a de Sitter state, not Em02-E’s relational lapse, not XVI-P’s QdS scheme, and not XVI-Q’s sigma-image record. No quantum coefficient is admitted.

Read against the standing problems
Standing problems. No standing problem is named in this text. It was still read against the nine problems and does not close any of them. The authors are OpenAI.

Proves Donovan's conjecture: over each fixed algebraically closed field of characteristic , blocks of finite groups with bounded defect-group order have only finitely many Morita-equivalence classes, for every prime . Also proves the integral form over each fixed complete mixed-characteristic discrete valuation ring with algebraically closed residue field.
We prove Donovan's conjecture over every algebraically closed field K of characteristic p > 0. For each fixed K and bound on defect-group order, blocks of finite groups represent only finitely many K-linear Morita equivalence classes. The defect groups need not be abelian, and the result includes p = 2.
