[mathwonk]

this seems to be the same book that was originally issued as Analysis II by Lang. I used this book in a beginning grad class in real analysis in 1971 or so, but i really blew my well meaning class away. Do not do this. This is a very abstract and advanced version of real analysis and deserves to be a second or third version of the subject. (His version of integration theory is not for real valued or even complex valued functions, but for Banach space valued functions, helloooo?) I loved Lang in person and I respect and treasure some of his books, but as a textbook writer he could really be an arsehole (see if this spelling escapes the obscenity checker).

I liked it though. You learn some cool stuff here. Decades later when one of my colleagues said he was working on fredholm operators, but did not expect me to know what they were, thanks to lang I said, sure those are just Banach space operators with finite dimensional kernel and cokernel, right?
