About the Workshop
Quantum field theory and String/M-theory have been major tools in shaping our theoretical understanding of the fundamental aspects of nature. Recently, there has been rapid progress in uncovering the deeper structure of these theories. This annual meeting of active scientists in East Asia provides an excellent opportunity to exchange ideas, discuss the latest developments, and explore cutting-edge research in the fields of string theory, quantum gravity, and quantum field theory. The meeting serves as a platform for fostering collaborations and collegiality, while facilitating progress in this exciting area of research, with the goal of deepening our understanding of the fundamental laws of nature.
