Re: Abstract: Workshop @ PSI

[Claude Petitjean <claude.petitjean@psi.ch>]

Lieber Bernhard,

ich denke, das Abstract toent wissenschaftlich sehr verheissungsvoll.
In der Mitte ("This description provides links pp-fusion ...") scheint mir
ein Wort ("provides") zu viel. Wahrscheilich weglassen.

Mit Gruss

Claude
