Terminology for notion dual to “support”
I don't know if this point is important, but usually, the support of $f$ is the closure of the set on which $f$ is non-zero (assuming some topology on the domain of $f$). |

sequences of plane measures converging to a singular one: terminology, etc
Correct. BY the way: The former ones (uniform measures on "full" triangles) are absolutely continuous w.r.t. Lebesgue measure. Probably also Lebesgue's decomposition theorem (en.wikipedia.org/wiki/Lebesgue%27s_decomposition_theorem) could be helpful. |

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? |
