How should an analytic number theorist look at Bessel functions?
Isn't there some $f$ missing in the formula for $\hat f$? |

eBook readers for mathematics
Another short update: I used it for several weeks now and I have to say that the battery lasts almost as long as for usual paper books. I basically never have to recharge. The time the ebook is connected with the computer to upload new stuff is almost enough to recharge. |

eBook readers for mathematics
A short update from my perspective: I uns the PocketBook Pro 912 and I am also very happy. It reads and rescales djvu and pdf. Cross-Refs in pdf still do not work. You take notes with a stylus but this is sometimes very slow. |

Convergence rate of fourier partial sum
Have you checked the reference which is given there? However, looks like off-topic here (see mathoverflow.net/faq). |

What functions can be obtained as a convolution of a Schwartz function and a tempered distribution?
Would you mind to show the argument? |

$\ell_o$ Minimization (Minimizing the support of a vector)
Still a question remains: What is the aim of your reformulation? In other words: what is wrong with the $\ell^0$-minimization problem? As you have written: The problem is NP-hard and hence, there will be no "easy" reformulation with out any further assumption on $A$ (unless $P=NP$). |

$\ell_o$ Minimization (Minimizing the support of a vector)
I am confused: Do you look for an exact reformulation or an LP relaxation? |

Colloquial catchy statements encoding serious mathematics
Not an exact duplicate. Here its about optimization and not about finance. |
