there are someone who's working on it...

<< Santos, Francisco (University of Cantabria, Spain) A counter-example to the Hirsch conjecture

Victor Klee came to the Department of Mathematics to talk to me. We had a nice conversation during which he asked "Why don't you try to disprove the Hirsch Conjecture?" This talk is the answer to that question.

I will describe the construction of a 43-dimensional polytope with 86 facets and diameter bigger than 43. The proof is based on a generalization of the $ d $-step theorem of Klee and Walkup. >>
