An Introduction to Four-Dimensional Chern-Simons Theory

Book info: An Introduction to Four-Dimensional Chern-Simons Theory (Hardcover, 348 pages) – World Scientific Publishing Company, 2026. Language: English.

The aim of this book is to provide a pedagodical yet comprehensive review of various aspects of four-dimensional Chern-Simons theory, a quantum field theory that has emerged as an organizing principle for various integrable systems, such as integrable spin chains, integrable lattice models, and two-dimensional integrable quantum field theories. Among topics covered are the derivation of the Yang-Baxter equation and its solutions, the Yangian algebra, realizations of two-dimensional integrable field theories and their Lax operators, string-theoretic embeddings of four-dimensional Chern-Simons theory, holographic duals of the theory, as well as dualities of integrable quantum field theories. Editorial Reviews About the Author Meer Ashwinkumar completed his PhD in theoretical physics at the National University of Singapore in 2018. He then worked as a postdoctoral researcher at the National University of Singapore and subsequently at the prestigious Kavli Institute for the Physics and Mathematics of the Universe, Japan. He has coauthored multiple research papers on string theory and quantum field theory that have appeared in leading journals. At present, he is an Advanced Postdoctoral Researcher at the Institute for Theoretical Physics, part of the Albert Einstein Center for Fundamental Physics at the University of Bern, Switzerland.
