Preface
This is quite a nonstandard “Solutions Manual,” but I use the term for lack of something more descriptively accurate. Many of the Problems and Complements don't ask questions, so they certainly don't have solutions; instead, they simply introduce concepts and ideas that, for one reason or another, didn't make it into the main text. Moreover, even for those Problems and Complements that do ask questions, the vast majority don't have explicit or unique solutions. Hence the “solutions manual” offers remarks, suggestions, hints, and occasionally, solutions. Most of the Problems and Complements are followed by brief remarks marked with asterisks, and in the (relatively rare) cases where there was nothing to say, I said nothing.
