SUMMARY:Joint PM/C&O Grad Colloquium
CLASS:PUBLIC
DESCRIPTION:PATRICK NAYLOR\, DEPARTMENT OF PURE MATHEMATICS\, UNIVERSITY OF
  WATERLOO\n\n“Is any knot not the unknot?”\n\nEver wanted to learn som
 ething about knots? This is your chance! We'll\ntalk about some basics of 
 knot theory\, including how to  prove some\nintuitively `obvious' but mat
 hematically tricky results.  Along the\nway\, we'll see knot coloring inv
 ariants\, polynomial invariants\, and\nmore. We'll even show how to produc
 e a knotted surface: a  sphere\n($S^2$) in $\\mathbb{R}^4$ that is `knott
 ed'. This talk will be very\naccessible and will include many cool picture
 s.
