Many dimensions plus linear algebra plus probability equals Random Matrix Theory.
Turns out to pop up in a lot of linear systems, and induce some elegant results, and be useful where linear algebra is (“the whole modern world”) therefore super trendy.
I mostly encounter this though matrix concentration, which is where most of the information is; This is a sideshow for my purposes.
