Adiprasito, Huh and Katz announce a proof of Rota's log-concavity conjecture
Professor Eric Katz of the University of Waterloo and his colleagues Karim Adiprasito (Max Planck Society and Hebrew University) and June Huh(Clay Mathematical Institute and Princeton University) have proved Rota's 45-year old conjecture on the log concavity of the characteristic polynomial of matroids.
