Wikipedia and other articles available online have no reference. Schauder's paper about his fixed point theorem is available online at


<http://matwbn.icm.edu.pl/ksiazki/sm/sm2/sm2114.pdf>


but, even if I don't speak a word of German, it seems to me that there is no reference.


In Brouwer's wikipage 


<http://en.wikipedia.org/wiki/Luitzen_Egbertus_Jan_Brouwer>


there are some references to Brouwer's papers, but only focused on his contribution to philosophy and philosophy of math.


Thanks in advance,


Valerio
