A Family of Counter Examples to an Approach to Graph Isomorphism


الملخص بالإنكليزية

We give a family of counter examples showing that the two sequences of polytopes $Phi_{n,n}$ and $Psi_{n,n}$ are different. These polytopes were defined recently by S. Friedland in an attempt at a polynomial time algorithm for graph isomorphism.
