I honestly don't understand several of the reviews here. At the one extreme, we have people who complain that there are not enough examples, and there are too many gaps in the proofs.
Well, that is partly the point. At some point in math, you have to move beyond the spoon fed approach of a typical lower division calculus textbook and fill in the gaps and figure out the examples for yourself.
At the other extreme, one person complained that the exercises were uninspired and did not lead away from the text. The only response I have to that is "are you reading the same text that I am?"
The title is not misleading. The book is a concise introduction to PDEs. One should have had some upper divison analysis, and some lower divison ODEs but that's about it.
I have had a graduate course in PDEs, which I basically failed to understand. I was able to get through the course, but without ever getting any "big picture". This is probably because I had never taken an undergraduate PDE course. I now have got to the point where I need to know undergraduate level PDEs and this textbook has been perfect. It is hard, but readable. The questions cover a lot of material and have a wide range of difficulty. As I've worked my way through the book, I feel that I am finally getting to grips with the subject, and beginning to see a big picture.
One of the better textbooks in my collection
