Gunnar Krug found a trivial error in my collection of theorems and formulas for the mathematical olympiad (see math documents). Updated the document, also improving the overall appearance a little bit. However, there’s still so many things I would do different if I wrote the document now (it’s been way back in 2004 or so). But sorry, haven’t got enough time to fix these things right now!
Just updated the homepage of our annual course at Graz University of Technology for participants of the Austrian Mahematical Olympiad (ÖMO). Every month there will be a Saturday of teaching various mathematical topics to students in the age between 15 and 18. I will talk about combinatorics in January and February 2010.
