Working problems is a crucial part of learning mathematics. No one can learn topology merely by poring over the definitions, theorems, and examples that are worked out in the text. One must work part of it out for oneself. To provide that opportunity is the purpose of the exercises. Let be a collection of connected subspaces of ; let be a connected subspace of . Show that if for all , then is connected. If there is a separation of the union, then and all lie within or (Lemma 23.2). Suppose, , then each , and is empty. Contradiction. Alternatively, the connected (by Theorem 23.3) subspaces share a point (apply Theorem 23.3 again). Below are links to answers and solutions for exercises in the Munkres (2000) Topology, Second Edition. Enjoy!
Here you can find my written solutions to exercises of the book Topology, by James Munkres, 2nd edition. They contain all exercises from the following chapters:
Unfortunately, I do not plan to write down solutions to any other chapter in the future. This is not an official solution manual. PDF Links: Chapter 2 – Topological Spaces and Continuous Functions. (Last Updated: 1 January 2021.) Chapter 3 – Connectedness and Compactness. (Last Updated: 1 January 2021.) Try to do the exercises by yourself first. Do not just copy solutions. Please be aware that I wrote down these solutions while I was still an undergraduate student some time ago, so they are more likely to contain errors. Please send comments, suggestions, corrections of errors/typos, etc, by e-mail, or as a comment in this webpage. You can mail me at |
