Here are the books I have written on mathematical physics.

**Instantons and large N**

*Instantons and large N*(Cambridge University Press, 2015) is, as its subtitle indicates, an introduction to these two non-perturbative methods in quantum field theory. The book is intended for graduate students and researchers.

**Chern-Simons theory, matrix models, and topological strings**

This book, published by Oxford University Press in 2005, is more specialized. I now realize that it should have contained much more background on the different subjects. It might be useful for experts or prospective researchers.

**Topological quantum field theory and four-manifolds**

This book, written with my former Ph.D. supervisor Jose Labastida, and published by Springer in 2005, was my first one. It is also quite specialized. Our goal was to provide a direct path from the basics to Witten's magic formula and to Moore and Witten's u-plane integral. It will be useful for people willing to learn the applications of supersymmetric gauge theory to four-manifolds, which constitutes one of the most dramatic successes of quantum field theory in mathematics.
