Quantitative lower bounds related to Zhang's theorem on bounded gaps
Does Zhang's result have any useful implications for previous polymath project, "Deterministic way to find primes"? |

Tightening Zhang's bound
I have an impression that this topic is more suitable for Polymath project: polymathprojects.org |

Can you re-edit equations with LaTeX? |

Sequences of Coefficients in $a p^i + b q^j = 1$
For every (i,j) pair there a lot of pairs (a,b) satisfacting this equation, so are there any other restrictions? Also, how explicit formula for them should be? Is something like $a_{ii}=p^{-i}\mod q^i$ acceptable? |

Nontrivial question about fibonacci numbers?
"Every sufficiently high (= high enough for the right hand sides to make sense)" - is this remark necessary? Because Fibonacci numbers could be defined for negative $n$. |

Formula for n-th iteration of dx/dt=B(x)
Is your expression for x(4) right? I re-checked my calculations, and the last coefficirnt isn't 7, it's 1. |

Formula for n-th iteration of dx/dt=B(x)
Hm, incidentally I made such calculations when prepared my thesis. I remember that the coefficients were somehow related to the Eulerian numbers. Unfortunately, I didn't find closed expressions. |

The difference of two sums of unit fractions
Well, actually he gave the bound - denominators should be no larger than $n$. |
