 * Do you see the sentence at the top of this page that says: "We don't do your homework for you, though we’ll help you past the stuck point"? Tell us what you are stuck on, and we might be able to help (though it would be better on the maths reference desk). --ColinFine (talk) 13:32, 7 December 2013 (UTC)


 * I'll give some tips.
 * Compact_space: first five lines should give the answer regarding "compact".
 * One of the properties of Countably compact space should tell you the rest.

 * merriam-webster.com gives the IPA transliteraration of "Tietze's" as \ˈtēt-səz-\ and has a sound file - I can't tell you if it works because some ne'er-do-well has borrowed my speakers and not returned them. There's another sound file on memidex.com. Alansplodge (talk) 00:43, 8 December 2013 (UTC)
