Q: I've found a
bug in one or more pages. What can I do ?
A: Please report any error to one of the
two authors, it will be corrected as soon as possible.
Q: There is
a formula or a result whose author is not quoted
A: We try, whenever it's possible, to
quote the author of any historical or important result, if we made a
mistake or forgot an attribution, please send us any reference and the
modification will be made.
Q: May I
suggest to insert a result or a new formula ?
A: Yes of course, we appreciate any
suggestion and we will consider it with attention.
Q: Was the
site written in html ?
A: No. Except for the presentation
pages, the original is in LATEX and we use the tth free
software to convert it in html. Even if the display of a formula
with html is not as nice as the representation of this formula
with a picture (gif, jpg,...), it has the advantage to be fast to
download.
Q: How can I
avoid font problems ?
A: On Mac, the conceptor of
tth the program which converts LATEX to html
suggests to use the MacRoman policy in your navigator to
eventually avoid problems. To be more precise and according to Jonathan
Sondow, set the Character Set to Western (MacRoman) if the browser
is Netscape Communicator, or to Western (Mac) with Internet
Explorer. In case of failure he also suggests to try Western
(Latin1) or Western (Windows). On other
platforms, font problems seem impossible to solve; a bypass exists on
some pages which are also available in a postscript version.
Q: Who are
the authors ?
A: We are located in France (Paris) and
are both graduates from french Grandes Écoles of Engineering and
one of us has a PhD in mathematics. We are currently working as computer
scientists in numerical analysis.
Q: Is the
content of this site copyrighted ?
A: Yes but you are free to read it,
print or used it for any private or educational usage. You can also
insert any part in a work (thesis, site,...) as long as you quote both
authors: Xavier Gourdon and Pascal Sebah. Any commercial
use must be done with the authors' agreement.
