The Kelmans-Seymour conjecture explained
Breakthrough! There was exciting news in the mathematics world recently, when it was announced that Xingxing Yu, Yan Wang and Dawei He from Georgia Tech proved the Kelman-Seymour conjecture. The 120-page paper containing the proof has been posted to the preprint server arXiv. Given the length of the paper, it will take time for reviewers to verify it. We…
Interview with a mathematician: Maria Chudnovsky
Maria Chudnovsky is a leading mathematician working in the field of graph theory. She was born in St. Petersburg, Russia in 1977, and moved to Israel with her family at the age of thirteen. Maria studied mathematics at Technion in Haifa. She completed her PhD at Princeton University in 2003, supervised by Paul Seymour. Maria has the most…
Interview with a mathematician: Richard J. Nowakowski
In the first of what I hope is an ongoing series of interviews with fellow mathematicians, here is my conversation with Richard J. Nowakowski. We sometimes just call him RJN for short. Richard works on graph theory and combinatorial game theory at Dalhousie University, where he is a University Research Professor. He completed his M.Sc. and Ph.D. degrees under…
