Independent and uniformly distributed on $(\frac{1}{2},1]$ What do you mean by "normally distributed on $(1/2,1]$? Uniformly distributed, perhaps? |

Is closure of a semigroup again a semigroup? @HagenvonEitzen: That is what I would suspect. What I was hoping for is a more elementary example to give some intuition how this particular piece of wishful thinking fails. |

Is closure of a semigroup again a semigroup? The one I know, and the one I am interested in primarily, is the \v{C}ech-Stone compactification of a discrete semigroup like $\mathbb{N}$. However, it is not very easy to get a hold on how things work there. |

What would be the immediate implications of a formula for prime numbers? The third formula blew my mind. Until now I was convinced that any formula for a prime has to either contain a parameter that cannot be effectively computed, or has to be immensely complicated. This one is so elegant! |
