abstract: |
Due to some intractability considerations, reasonable
formulation of necessary and sufficient conditions for
decomposability of a general multigraph
G
into a fixed connected multigraph
H
, is probably not feasible if the underlying simple
graph of
H
has three or more edges. We study the case where
H
consists of two underlying edges. We present
necessary and sufficient conditions for
H
-decomposability of
G
, which hold when certain size parameters of
G
lies within some bounds which depends on the
multiplicities of the two edges of
H
. We also show this result to be "tight" in the sense
that even a slight deviation of these size parameters from
the given bounds results intractability of the
corresponding decision problem.

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.
