Starting with May 2007, I will be posting new problems into the Open Problem Garden which was designed in SFU in 2006/07 by Matt DeVos and Robert Samal and included discussions of our research graph theory group at SFU. The Open Problem Garden is a Wikipedia-type forum devoted to open problems in Mathematics and with its current orientation to cover at least the area of graph theory. Most of my older problems will be added over time to this site.
