Since March 2023, Qiuzhen College has held several Tsinghua Open Problems Seminars (TOPS). We identify cutting-edge issues in the current field of mathematics, invite top scientific researchers at home and abroad to Tsinghua to give lectures, and conduct face-to-face exchanges and discussions with teachers and students of Qiuzhen College. In addition, we have provided students with abundant research materials and established a vital platform for students to understand the frontiers of mathematical science and embark on the journey of scientific research and truth-seeking.
