Source paper: released examination archive, member 2014/T/a13757w1.pdf. The original cover dates the examination to 24 June 2015, 9.30am to 11.00am. The folder name is not the examination year.

The complete three-page replacement is in the Mathematics Part A FOI release, member FOI-20210708-1 - Data/a13757w1 (5).pdf. Its intact pages 2–3 establish the complete three-question tree. The answers below replace the provisional fragments with full solutions to all 23 verified leaves, including the previously unavailable simplicial-complex and surface-classification material. The original archive link above is retained for provenance.

Complete source recovery: additional Oxford examination release, member FOI-20210708-1 - Data/a13757w1 (2).pdf, supplies all four printed pages, including questions 1–2 missing from the earlier copy. Questions 1–2 are solved below; the five existing solutions to question 3 are retained unchanged.

Answer availability checked on 28 October 2026: no exact-paper or selected-part solution advertisement was found in a bounded search of official Oxford sources. Oxford states that odd-year examination solutions are not released apart from the 2019 exception.^[ref]

Topology and Groups, Tuesday 1 June 2010, 2.30pm–4.00pm. The cover cross-lists Mathematics and Mathematics and Philosophy Parts B and C under the printed label C3.1a. This complete four-page scanned paper was supplied through the past-papers disclosure, in original Part C bundle pages 317–320. Every source page and the labelled covering graph were read directly; the private editable transcription includes all text and an editable reconstruction of that graph. No exact worked-answer advertisement was found in the bounded availability check.

Topology, Groups and Algebraic Topology, Mathematics Parts C and B and Mathematics and Philosophy Part C; Wednesday 30 May 2007, 9.30am–12.30pm. The complete five-page source and both sections are privately transcribed from original Part C bundle pages 15–19, supplied through the past-papers disclosure. No exact worked-answer advertisement was found in the bounded availability check. Homology and cohomology use integer coefficients unless another coefficient group is stated.

Topology and Groups and Algebraic Topology, Trinity Term; Wednesday 3 June 2009, 2.30pm–5.30pm. The intact cover lists Mathematics Part B, Mathematics Part C, and Mathematics and Philosophy Part C under the same module code. Both sections and all six questions are covered here. The full five-page source is retained in a private editable transcription. It was supplied through the past-papers disclosure, in original Part C bundle pages 222–226. No exact worked-answer advertisement was found in the bounded check.

This University of Oxford Part B paper is cross-listed for Mathematics and Mathematics and Statistics. Section A concerns mathematical biology, and section B concerns dynamical systems. ^[ref] The archive contains the complete editable eight-page transcription. Bounded searches of official sources found no advertised answers to this exact paper. The original solutions cover every source leaf and every unnumbered task in questions 5–8.

This University of Oxford Part B paper covers Mathematical Ecology and Biology in section A and Nonlinear Systems in section B. It is cross-listed for Mathematics, Mathematics and Computer Science, and Mathematics and Statistics. ^[ref] A bounded official-source search found no advertised answers for this exact paper. The complete archive transcription retains its supplied graph and printed map; the solutions include the antipodal two-cycle lost by the proposed quadratic reduction.

This University of Oxford Part B paper covers Mathematical Ecology and Biology in section A and Nonlinear Systems in section B, and is cross-listed for the Mathematics, Mathematics and Computer Science, and Mathematics and Statistics degrees. ^[ref] A bounded search of official sources found no advertised solutions for this exact paper. The complete seven-page archive transcription preserves the printed notation; the solutions explain the initial-data restrictions, omitted Neumann zero modes and zero-frequency exception where needed.
