However, I'm not sure what its niche is -- what this book provides that others don't, or that it covers more thoroughly. If you want math, read Simon and Blume or a math book. If you want micro theory, read Mas-Collel or Silberberg. If you want neoclassical macro theory, read Sargent. For optimal control, read Kamien/Schwarz or Seierstad/Sydsaeter. This book covers selected topics from each. Though it covers them well, much is left out.
Noticeably absent from the book is any uncertainty, randomness, or probability. There is also no game theory. These seek huge omissions for a book which seeks to show the usefulness of mathematical techniques in economic analysis.
Notation is also a bit unusual. I was a bit confused by some of the author's own notation for partial orderings and Cartesian products.

This book attempts to introduce some of the mathematical tools that are relevant to economics (espically micro). Proofs of the theorems are mostly omitted. There is a chapter introducing or reviewing some basic mathematics. Main topics are non-linear programming, uncertainty, differential equation and optimal control theory.
The treatment on non-linear programming is excellant. It is a good book for graduate students major in economics. But it requires some basic knowledge in mathematics.
