More than ten years ago, when I first put this website online, I received a lot of nice messages from the advice to the congratulations. I had been very touched by so much kindness and interest to this work. To those people and those who spread this adress over the internet, many thanks.

In particular, thanks to my dad (a writer) and mom, old books seller in Nîmes for their support. Many times, mom offered me some pretty old fascinating books in maths such as courses at Polytechnique by Camille Jordan (1891-1892) and Gaston Julia (1956), delightful !

Thanks to "Des trucs et des maths" for the background !

And, of course, thanks to the patient English translators who helped for this project to be achieved, I mean Florian Bouyer (first prize from the jury ), David Jelgersma, Guillaume (Bobest3g), Thomas Robitaille and myself ;-)
