Readers reviews:
*This book taught me more than I know (anymore) about differential equations. It is an intense and pretty comprehensive text. That means it is not an easy read, given that it deals with a rather hard subject.
Recommended for all math majors and others who need in-depth knowledge of "analog" (i.e., non-discrete) mathematics.

*An invaluable instruction to Applied Mathematics as the language to approaching the essence of Physics and Modern Engineering. A balance to the today overcomputerized mathematical methodology.
