deal.II mailing list members

We thank the numerous people sending questions, suggestions, bug reports, bug fixes and improvements. deal.II would be much less without their contribution.

History

deal.II draws from some ideas which were first implemented in the predecessor library, DEAL, developed by Guido Kanschat, Franz-Theo Suttmeier, and Roland Becker. This library is now being maintained by Franz-Theo Suttmeier at the University of Siegen, Germany.
