| abstract: |
We consider simply generated trees, where the nodes are
equipped with weakly monotone labellings with elements of
{1, 2, …, r}
, for
r
fixed. These tree families were introduced in
[ProUrb1983] and studied further in [Kir1984], [Bli1987],
and [MorPro2005]. Here we give distributional results for
several tree statistics (the depth of a random node, the
ancestor-tree size and the Steiner-distance of
p
randomly chosen nodes, the height of the
j
-st leaf, and the number of nodes with label
l
), which extend the existing results and also contain
the corresponding results for unlabelled simply generated
trees as the special case
r=1
.

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.
