Since September 2013, I am a postdoctoral researcher at the Royal Institute of Technology (KTH), mainly working in random matrix theory.
I obtained my PhD degree from KU Leuven (Belgium, with Arno Kuijlaars) jointly with the University of Toulouse (France, with Michel Ledoux).

Simple Spectrum of Jacobi matrices
Because the spectrum of an nxn truncation of a Jacobi matrix has for eigenvalues the zeroes of a degree n orthogonal polynomial, read the literature on OPs. |

Geometric interpretation of the average of two independent Cauchy distributions
Can you precise what you mean by "average" ? |

rigidity of eigenvalues of circular ensemble
@JohnJiang You're the welcome. I don't know what you have in mind, but I think this type of questions is interesting and I'd be glad to discuss more about it; please write to me at ahardy(you know what)kth.se |

Statistical models in terms of families of random variables
I'm kind of lost: as Michael Greinecker recalled, you can always build a huge probability space in which all your variables live, whatever $\Theta$ is, thanks to the tensor product construction. Then, maybe the "natural" topology you look for just the convergence in distribution of random variables ? In this case, that $x:\Theta\rightarrow L$ is continuous is by definition equivalent to $P:\Theta\rightarrow \Delta(X)$ continuous. But maybe I misunderstood the question. |

A sufficient condition for a probability measure to have compact support
Yes, it does ! By any chance do you know if there is a similar characterization involving $C_\mu$ ? |
