Line 185:

"Differentiating under the sign of integral it is not difficult to check that ''φ′(t)=0'' for all ''t''" — really? How to check it? Maybe the Milnor-Rogers-Gröger approach is meant? There, ''φ'' is polynomial (not just smooth) and appears to be constant near 0, therefore everywhere. [[User:Tsirel|Boris Tsirelson]] ([[User talk:Tsirel|talk]]) 08:51, 15 September 2015 (UTC)

Hello fellow Wikipedians,

I have just added archive links to {{plural:4|one external link|4 external links}} on [[Brouwer fixed-point theorem]]. Please take a moment to review [https://en.wikipedia.org/w/index.php?diff=prev&oldid=709120241 my edit]. If necessary, add {{tlx|cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{tlx|nobots|deny{{=}}InternetArchiveBot}} to keep me off the page altogether. I made the following changes:
