This needs considerable tedious hard slog to complete it.In particular: Arrange into some semblance of order, subcategorise the abstract algebraic definitions as normal, and perhaps sub-page where it looks appropriate, e.g. Definition:Left (Abstract Algebra)To discuss this page in more detail, feel free to use the talk page.When this work has been completed, you may remove this instance of `{{Finish}}` from the code.If you would welcome a second opinion as to whether your work is correct, add a call to `{{Proofread}}` the page. |
