Hirsch Conjecture Counterexample 3

January 21, 2011

There is a counterexample to the Hirsch conjecture in 20 dimensions. The lowest number of dimensions that I was aware of previously was 23. See this post. Also There is a web page here, a poster for the IPAM conference here.

The IPAM congress also has a couple of presentations
related to polymath3. The IPAM congress schedule is here. There are two talks related Polymath3. One abstract is here, the other here.
