The 5th China-Brazil Symposium on Applied and Computational Mathematics was held in Songshan Lake Science City from August 23rd to 24th, 2021. The Symposium was co-sponsored by the Chinese Mathematical Society and the Brazilian Society of Applied and Computational Mathematics. It was co-organized by the Chinese Society for Computational Mathematics, and hosted by the School of Computer Science and Technology of DGUT. The two-day symposium was supported by the Department of Mathematics and Physics of National Natural Science Fund of China and the Songshan Lake Hi-Tech Industrial Development Zone Administrative Committee. The Symposium, which attracted many academic scholars from China and Brazil, aimed to strengthen and promote exchange of knowledge and dialogue among experts in the fields of applied and computational mathematics, and serve as a platform for mutual exchange, discussion, and cooperation between Chinese and Brazilian experts and scholars. During the two days, the Symposium was held in an “online + offline” combination mode to facilitate detailed discussions on cutting-edge topics in the fields of optimization, numerical algebra, and scientific computing. All participants jointly promoted the research and application of applied and computational mathematics.

“The year 2021 marks the 47th Anniversary of China-Brazil Diplomatic Relations. The Symposium successfully promoted the exchange and cooperation between Chinese and Brazilian experts and pushed the development of applied and computational mathematics. This cooperation also demonstrates to the world that the comprehensive strategic and cooperative partnership between China and Brazil is expanding”, a significant person-in-charge reported.
