The Ninth Shanghai International Symposium on Nonlinear Sciences and Applications (Shanghai NSA'23) will be held at Hexi University in Zhangye, Gansu Province, China, from 23 July to 28 July, 2023.

Shanghai NSA'23 is sponsored by the Shanghai Society of Nonlinear Sciences, co-sponsored by the Shanghai Center for Nonlinear Sciences, organized by the Research Institute of Intelligent Complex Systems of Fudan University, the School of Mathematical Sciences of Fudan University, co-organized by Hexi University, and supported by the National Natural Science Foundation of China.

Nonlinear science is one of the focusing research fields and most active scientific frontier in this century, and Shanghai NSA'23 is devoted to this important area of scientific research. The theme of the symposium is intended to be broad enough so as to cover most of the directions in nonlinear science, with the aim of promoting wide interactions among researchers from different academic disciplines who are interested in nonlinear science and related technologies. The symposium will provide both experts and newcomers from different research backgrounds with an excellent opportunity to review the latest progress and development in the field of nonlinear science, and to exchange their experience, progress and ideas. The symposium will consist of both plenary talks and parallel sessions in six days.
