Starting with the first issue in January 2008, M2AN will be selecting certain papers as “Highlight papers” from time to time. We believe that these papers will be of particular interest to our readers due to the topic or approach pursued or perhaps the reach and implications of their results. “Highlight papers” will be briefly introduced by one of the Editors-in-Chief, and will be available (without charge and indefinitely) on the M2AN electronic site.
