I am just watching Carl Bender's Mathematical Physics video lecture course (about asymptotics and its application in physics)
http://www.perimeterscholars.org/328.html
which is great!
Are there any lecture notes for this great course uploaded somewhere? After watching the videos, I'd like to reconsider the course in detail.
I Prof. Carl Bender has written a book about mathematical physics dealing with some of the methods he explains in the course, but I would prefer lecture notes that exactly follow this course first.
This book: Advanced Mathematical Methods for Scientists and Engineers: Asymptotic Methods and Perturbation Theory
