Have only scanned it, but it seems well motivated and readable.
- ximeng 5y agoThis is exactly the kind of thing I'm thinking about, thank you. It still looks challenging but certainly more accessible than the original.
- gilleain 5y agoThis is great. Not only the acknowledgements section to MathOverflow (as mentioned in another thread) but also the section with a drawing of an elephant > Incidentally, in earlier drafts of the paper, we did not have a “writer” and a “reader”, but a mahout and an elephant <<picture of man and elephant>> They were unfortunately censored by my coauthor. As this is my exposition, here they are :)
