    • Christophe Biernacki  (Laboratoire Paul Painlevé, Univ. Lille 1 et INRIA)
    • Vincent Brault (Laboratoire Jean Kuntzmann, Univ. Grenoble Alpes)
    • Gilles Celeux  (Laboratoire de Mathématiques d’Orsay, Univ. Paris Sud et INRIA)
    • Elisabeth Gassiat  (Laboratoire de Mathématiques d’Orsay, Univ. Paris Sud)
    • Van Hà Hoang  (Laboratoire de Mathématique Raphaël Salem, Univ. Rouen Normandie)
    • Hajo Holzmann  (Philipps-University Marburg, Germany)
    • Dimitri Karlis  (Department of Statistics, Athens University of Economics and Business, Greece)
    • Trung Tin Nguyen (LMNO, Univ. Caen Normandie)
    • Andrea Rau  (Département de Génétique Animale, INRA, Jouy en Josas)
    • Pierre Vandekerkhove  (Laboratoire d’Analyse et de Mathématiques Appliquées, Univ. Paris-Est Marne-la-Vallée)
    • Cinzia Viroli  (Department of Statistical Sciences, Universita di Bologna, Italia)

Unfortunately, since this is my former department, I will not be able to attend as I am taking part into the SIAM Conference on Uncertainty Quantification (UQ20), on the very same days. In a session on likelihood-free inference.

a very quick Riddle

A very quick Riddler’s riddle last week with the question

Find the (integer) fraction with the smallest (integer) denominator strictly located between 1/2020 and 1/2019.

and the brute force resolution

for (t in (2020*2019):2021){ 
   a=ceiling(t/2020)
   if (a*2019<t) sol=c(a,t)}

leading to 2/4039 as the target. Note that

\dfrac{2}{4039}=\dfrac{1}{\dfrac{2020+2019}{2}}

“extremely damaging and slanderous blog article”

Posted in Books, pictures, University life with tags , , , , , on April 13, 2019 by xi'an

Yesterday was a first for the ‘Og in that my university legal department received a complaint from a company about one of the posts, that among other things was considered as an “offending” and “extremely damaging and slanderous commentary” on the services proposed by this company, including posting the unsolicited marketing email it has sent me earlier and which induced this comment of mine.  Written in superb legalese of course. As my point had been made when the blog was posted, a while ago, and as I saw no point in bothering my legal department representatives or wasting further time on such nonsense, I removed this terribly damaging entry and hope the poor dears have recovered by now… It’s “a mere attempt at bloggin’, nothing more”, right?!

Merci, Simone! [in Strasbourg]

I posted this picture on the ‘Og last June, when I went to Rouen. At the time Simone Veil had just passed away and I wanted to recall her single-handed fight for making abortion legal in France… I received last week an email I first took for a spam, email from a curator of the European Parliament, in Strasbourg (where Simone Veil was for a while a European deputy and its President, its first female President), preparing a permanent exhibit in her memory and wishing to use my picture in the exhibit, to illustrate another perspective on her, away from official and family photographs. Completely unexpected, but I obviously gave immediately my agreement.

Merci, Simone!
