<a href="https://www.youtube.com/watch?v=86uarqPBJ9s">Waiting room video</a>: an account of the Brouwer Fixed-Point Theorem.<br><br>

Stated and proved Brouwer's fixed-point theorem. The Frobenius-Perron Thoerem (or at least a version of it) was proved as an application of Brouwer's result.  So topology and algebra really are very related!
