I recently posted questions on mathoverflow about chessboard complexes and on TCSexchange about Markov chains on 3-colorings of cycles. There's actually a (t... |

A major progress on an old standing beautiful problem.Aubrey de Grey proved that the chromatic number of the plane is at least 5. (I first heard about it from Alon Amit.) TheHadwigerNelson problem asks for the minimum number of colors required to color theplanesuch that no twopointsat distance one from each other have the |

Your GPU doesn't know what a cylinder is. It knows triangles! That's it. Three points, maybe a color. The entire vocabulary of graphics hardware fits on an inde |

The rational numbers $latex {\mathbb{Q}}&fg=000000$ are dense in the real numbers $latex {\mathbb{R}}&fg=000000$. The cardinality of rational numbers in the interval $latex {(0,1)}&fg=000000$ is $latex {\boldsymbol{\aleph}_0}&fg=000000$. We cannot list them in ascending order, because there is no least rational number greater than $latex {0}&fg=000000$. However, there are several ways of enumerating the rational numbers. The... |
