Itai Benjamini: Coarse Uniformization and Percolation & A Paper by Itai and me in Honor of Lucio Russo
Here is another video of a smashing short talk by my dear friend Itai Benjamini with beautiful conjectures proposing an important new step in the connection between percolation and conformal geometry. Here is the link to Itai’s original paper Percolation … Continue reading
Bálint Virág: Random matrices for Russ
You can watch now all the videos for Russfest Elegance in Probability. Many great talks! I just watched Bálint Virág‘s lecture “Random matrices for Russ”. Highly recommended.
