Mathematician Disproves Hedetniemi’s Graph Theory Conjecture
From the article: "Now that mathematicians know Hedetniemi’s conjecture is false, the natural next question is just how false it is..."<p>And from Stanislaw Lem works (Cyberiad): "Everyone knows that dragons don’t exist. But while this simplistic formulation may satisfy the layman, it does not suffice for the scientific mind."<p>Time to read some Lem again?.. ;)
