A variant of Goldbach Conjecture
It can, but it could be a little tricky - most of the weights I use are not compactly supported (though they decay very fast -- they are almost supported on a compact interval). |

It would, but that's hard. See terrytao.wordpress.com/2012/05/20/… |

Packing bounds for sumsets, or, very discrete balls
Excuse my ignorance - is the rate for a linear code with minimum distance $n/3$ bounded from below by a positive constant? |

Heehee. Sure. Answer it in $\mathbb{F}_3^n$ if you prefer. |

HJRW - this (= going over a ball in the Cayley graph) is actually how I am producing drafts of posters right now. I still think it would be nice to know a priori how far one needs to go. |

Well, one can take care of the region $\Re(y)>1$ in the obvious way, and then apply a Monte Carlo method like this one to the rest. Still, this isn't really that satisfying. |

This is a good idea, but I'd still like to have an explicit bound. $2 A(S)/\epsilon$ (where $A(S)$ is presumably the Euclidean area of $S$) can be pretty large. |

In the case of a box $\lbrack 0,N\rbrack \times \lbrack 0,N\rbrack$ (a good example, actually), the hyperbolic area of $S$ is $\infty$, yet the question still makes sense. So, you really have to know what $S$ is. (And as I said, you may assume it is a box.) |
