It is our great honour to welcome you to the International Conference on Partial Differential Equations-Silkroad Mathematics Center Series International Conferences, hosted jointly by the Chinese Mathematical Society and the Academy of Mathematics and Systems Science, CAS. This conference brings together nearly 100 high-ranking guests from the members of the Silkroad Mathematics Center of Chinese Mathematical Society (SMC-CMS). Our first conference will focus on Partial Differential Equations and developing new and strengthen existing relationships between organizations and across the international science community. We hope this meetings contributed greatly to the development of the Silkroad Mathematics Center of CMS. We are confident that the conference will benefit from the same dedicated effort and spirit of cooperation established at the regional level.On behalf of CMS and AMSS, we are pleased that you have accepted the invitation to join us in Beijing, China’s historic capital city. We look forward to the engaging discussions, exchanges of ideas, and to the major outcomes of the Silkroad Mathematics Center Series International Conferences.
