I am an assistant professor at the Air Force Institute of Technology. My research tends to involve matrix design and algorithms for modern inverse problems.

Notion of manifold curvature?
Yes, it is. I didn't know how to describe the second Fréchet derivative without clunky use of the word "Hessian." Looking at wikipedia, it seems I could have just said "Hessian." |

Nearby matrices have nearby leading eigenvectors?
@FelixGoldberg - My particular application concerns PSD matrices, but perhaps you can link to a survey or something? |

Weil's Riemann Hypothesis for dummies?
Thanks! Do we know what $c_1(d)$ is, or do we have a bound in terms of $d$? |

Is this statement which relates the Fourier transform of a function to its singularities correct?
Note that $\cos(at)$ and $\sin(at)$ also sound the same (and yet are orthogonal). This is because your ear encodes the sound wave by having different parts of the basilar membrane resonate with different frequencies; as such, you effectively hear the spectrogram, i.e., your ear is "blind" to global phase, as Noah Stein suggested. This is a crucial idea in speech processing, see for example "On signal reconstruction without phase" by Balan, Casazza and Edidin. |

Is it easy to produce hard-to-color graphs?
Joel - Regarding your final comment "in which nearly every instance is hard", are there any well-known problems which are known to have this property? |
