Special issue in computing and visualization in science (CVS), related to the European multigrid conference, EMG 2010

With great pleasure we present the special issue in CVS related to the European Multigrid conference, which took place on the island Isola d’Ischia in Italy from 19 to 23 September, 2010. The conference was organized by Alfio Borzi (at that time at the Università degli Studi del Sannio, in Benevento, Italy, now at the University of Würzburg, Germany), and Cornelis Oosterlee, from the CWI—Center for Mathematics and Computer Science in Amsterdam, and the Delft University of Technology in the Netherlands. In fact, we have two special issues in two journals, as both organizers are handling editors of different journals. Next to this issue in CVS, we will have a second one in the journal Numerical Mathematics: Theory, Methods and Applications (NM-TMA). Both issues appear at approximately the same time, and contain seven contributions each, which makes fourteen special issue publications related to EMG2010 in total. TheEMGconference series provides a forum for researchers to present and discuss recent advances on the development, theory, and application of multigrid, multilevel, and multiscale methodologies. Previous EMG conferences were held inCologne (1981, 1985), Bonn(1990), Amsterdam (1993), Stuttgart (1996), Gent (1999), Hohenwart (2002), Scheveningen (2005), Bad Herrenhalb (2008). With the
