I just watched a video of James Gates and he discussed something he called the Gross Perrywall phase transition. It was named after David Gross, I am assuming most of you are familiar with his work. In an attempt to search more about this I came up empty. I do not know if I am spelling it correctly or not, but I found zero results. Does anyone here know what I am talking about? Better yet, any good videos you would recommend along the lines of this? Thank you for your time!
