Mirror Symmetry and Algebraic Geometry (Mathematical Surveys and Monographs)

This is a very specialized text focusing on the marriage of mirror symmetry - a powerful concept that arises in String Theory - and the language of Algebraic Geometry. The book motivates the subject with an introduction to the Physics wherein such questions arise, and therefore keeps things in prespective.

This book is one of the few monographs on mirror symmetry that is not a collection of articles written by specialists. It attempts to put mirror symmetry on a mathematically rigorous foundation and does so to a large degree. The book opens with a review of the motivations for mirror symmetry in quantum field theory and superstring theory. The content of this chapter is straightforward reading for physicists/string theorists but mathematicians may have trouble with the physical reasoning employed. The chapter explains the motivation for the mathematical constructions performed in the rest of the book. The author does a good job of presenting the mathematics in a form that is as rigorous as possible. The predictions made by physicists to quantities in in algebraic geometry are too interesting from a mathematical standpoint to let lay couched in the formalism of path integrals. The book gives many examples of mirror symmetry constructions that are rigorous mathematically, most of these involving toric varieties. A general methodology for finding the mirror of a given Calabi-Yau manifold is still unknown according to the author. By far the best chapter in the book is the one on quantum cohomology, as this tool has so many applications in algebraic and symplectic geometry. One is always impressed on the originality and breadth of ideas that have been employed in this subject. There are several topics in mirror symmetry that are not discussed in the book, but even with these omissions, this is a fine addition to the literature on the subject. One question that immediately arises when thinking about mirror symmetry is there is anything that is interesting in the case of Calabi-Yau manifolds over finite fields. The special case that comes to mind is for elliptic curves. Are mirrors of Calabi-Yau manifolds easier to find in the finite field case and does the mirror have a group operation related to the one on the original manifold (elliptic curve)? These questions are not addressed in this book, but answering them may have important ramifications for applications of mirror symmetry to the field of cryptography for example.

The authors talk about an important aspect of mathematics, the mirror symmetry. Here they explicate the duality between two space. They can be Kahler, Fano, Calabi-Yau. So we apply those results to quantum physics.
