I’m speaking on an “open problems” panel in honor of Dick Gross’s 60th birthday. I’ve got 10 minutes. I think I know what I’m going to say, but I was just informed that the panel is to be allowed to run late if audience interest demands it. So I thought it would be good to stock up a little more material. And it occurred to me this might be a good opportunity to blogsource! So, readers: if you were going to promote an open problem in front of Dick Gross and his wellwishers, what would it be?
