| keywords: | polytope, bistellar flip, triangulation, enumeration |
| abstract: |
A triangulation of a finite point set
A
in
R
is a geometric simplicial complex which covers the
convex hull of
d
A
and whose vertices are points of
A
. We study the graph of triangulations whose vertices
represent the triangulations and whose edges represent
geometric bistellar flips. The main result of this paper is
that the graph of triangulations in three dimensions is
connected when the points of
A
are in convex position. We introduce a tree of
triangulations and present an algorithm for enumerating
triangulations in
O(log log n)
time per triangulation.

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.
