Vol. 16 No. 2 (2021)

Volume 16 No. 2 (2021) is a special issue for the proceedings of The Banff International Research Station workshop entitled "Homogeneous Structures, A Workshop in Honour of Norbert Sauer's 70th Birthday" which was held from November 8th to November 13th, 2015.

Norbert Sauer is one of the three founding co-editors-in-chief of Contributions to Discrete Mathematics having served in that capacity since Volume 1 Number 1 (2006).

I want to thank Lionel Nguyen Van Thé, Institut de Mathématiques de Marseille, for taking on editorship of this special edition, soliciting contributions, having them refereed, and getting the final \tex files for technical editing. Lionel also prepared a summary of various open problems that were discussed in problem sessions at the workshop. The summary is a feature of this issue.

Robert Woodrow, Managing Editor.
