Does a product of matrices have eigenvalue 1
This depends crucially on the set of sequences that you are interested in. Is it all sequences of length $k$? If not, what? |

Drawing lines and removing squares - an Alice and Bob game
The proper questions to ask are: Given $N$, which player wins? And how? |

Some weird “system” of inequalities in nonnegative integers.
You should not have responded so quickly to SPG's question! $i≤j≤k≤l$ is not consistent with $1≤i,j,k,l≤17$. |

What is the protocol for making modifications to someone else's proof to prove something slightly stronger?
Erdős, not Erdös. |

what is the meaning of “consecutive triple points”?
Are you sure it said that? It's not proper English. |

Reducing factoring prime products to factoring integer products (in average-case)
You are being sloppy here. N = PQ can always be factorised -- it just can't be factorised (as far as we know) in polynomial time (with non-negligible probability). |

Which conjectures only need the Grand Riemann Hypothesis to become genuine theorems?
The Wikipedia article (en.wikipedia.org/wiki/Grand_Riemann_hypothesis) has this wonderful remark: "The Siegel zero, conjectured not to exist, is a possible real zero of a Dirichlet L-series, rather near s = 1." |

real roots for polynomials
@Willie: I think $Q_k$ is just the quotient when $P_{k-1}$ is divided by $P_k$. |

Rolling-ball game
Let's not forget that there are three possibilities: 1. There exists an infinite game. 2. There exist arbitrarily long finite games. 3. There exists $n$ such that no game is longer than $n$. So gowers and Gerhard could both be right, on the sphere and not just the torus. @Joseph: Nice pictures! |
