| abstract: |
Ordinary generating series of multiple harmonic
sums admit a full singular expansion in the basis
of functions
{(1-z)
, near the singularity
α
log
β
(1-z)}
α∈ℤ, β∈ℕ
z=1
. A constructive proof of this result is
given, and, by combinatoric aspects, an explicit
evaluation of Taylor coefficients of functions in some
polylogarithmic algebra is obtained. In
particular, the asymptotic expansion of multiple
harmonic sums is easily deduced.

The first source gives you the `gzipped' PostScript, the second the plain PostScript and the third the format for the Adobe accrobat reader. Depending on the installation of your web browser, at least one of these should (after some amount of time) pop up a window for you that shows the full article. If this is not the case, you should contact your system administrator to install your browser correctly.
Due to limitations of your local software, the two formats may show up differently on your screen. If eg you use xpdf to visualize pdf, some of the graphics in the file may not come across. On the other hand, pdf has a capacity of giving links to sections, bibliography and external references that will not appear with PostScript.
