On the afternoon of September 15th, the first lecture of the "Famous Teachers' University Lecture Hall" series of lectures for the fall semester of 2021 was held in the cloud as scheduled. This lecture is co-sponsored by the School of Mathematical Sciences and the Institute of Applied System Analysis, Jiangsu University. The guest speaker is the top expert in the field of invariant geometric flow and integrable systems-Dean Changzheng Qu from the School of Mathematics and Statistics of Ningbo University. More than 20 teachers and students from Jiangsu University, including Professor Zhitao Zhang, Professor Jun Wang, and Professor Wenxia Chen attended the report.

Before the lecture, Dean Zhitao Zhang gave a brief introduction to Professor Changzheng Qu and presided over the lecture.

Professor  Changzheng Qu gave a wonderful summary academic report on the topic of "Integral systems and invariant geometric flows in affine-related geometries", which mainly involved geometric flows and integrable systems, center and other affine and affine geometries, and symplectic structures. Affine geometry and the corresponding heat flow. Firstly, Professor Qu introduced some special geometric transformations and transformations in integrable systems, as well as group action invariant differential equations and invariant functionals. Subsequently, the invariant geometric flow and the integrable flow in affine geometry such as the center are further introduced, and the geometric explanation of the Hamilton structure and Miura transformation is given. Finally, the heat flow in affine geometry such as Euclidean geometry, affine geometry, center, etc., and related research results are introduced.

In the report, Professor Qu gave the profound connection between integrable system and geometric flow, reflecting his profound mathematical skills. Professor Qu's research work aroused great interest and attention of the teachers and students present. After the report, Professor Qu gave patient and meticulous answers to the mathematics questions that everyone was concerned about, and the teachers and students on the scene benefited a lot.

Finally, Dean Zhitao Zhang made a concluding speech for the lecture.

The “Lecture Hall of Famous Teachers” brand activities established by our school will continue to be carried out. By regularly inviting well-known experts, academic authorities, and outstanding young scholars in the subject field to give lectures. Continuously improve graduate students' mathematical literacy and scientific research and innovation capabilities, strengthen exchanges and cooperation between scholars, and further enhance the academic influence of the subject.
