Riemann hypothesis and other great conjectures in Mathematics

I wrote a paper Sketchy Tweets: Ten Minute Conjectures in Graph Theory that appeared in the Mathematical Intelligencer about famous conjectures in graph theory, all of which can be tweeted. Many of the big problems in graph theory are easy to state, but very hard to settle. It was great fun writing the article, co-authored with good friend and colleague Richard Nowakowski. We were inspired by Meyniel’s conjecture on the cop number, and we had excess energy from just having published our book The Game of Cops and Robbers on Graphs.… Read More Riemann hypothesis and other great conjectures in Mathematics
