2022年11月21日,发展中国家科学院第16届学术大会暨第30届院士大会在浙江杭州开幕,公布了新增选的50位院士。中国科技大学叶向东院士和中国科学院数学与系统科学研究院杨翠红研究员当选。
叶向东院士的研究工作涵盖了拓扑动力系统、遍历理论和其应用方面的许多重要课题。准确地说,叶向东与合作者建立了一个涉及幂零结构的极小系统的新结构定理;在多重遍历平均逐点收敛问题上取得了突破;证明了极小系统的最大无穷步幂零因子的某个几乎1-1扩充是其拓扑特征因子,这个结果可用于解决动力系统和组合数学中的几个长期未解决问题。此外,叶向东与合作者在Sarnak猜想、局部熵理论和动力系统的混沌行为等相关的问题上也做出了重要贡献。由于他的出色工作,他于2013年获得了中国数学学会颁发的陈省身奖,2018年获得了国家自然科学奖二等奖,2019年被增选为中国科学院院士,2020年获得何梁何利科学与技术进步奖。
杨翠红研究员是国际国内投入产出(IO)领域的著名专家。开发了多个投入产出技术模型并将其成功应用于对外贸易与全球价值链、粮食安全、水利投资、宏观经济分析和能源利用等重大问题研究,有效支持了相关决策。她是TWAS成思危经济科学奖、国家青年科学技术奖、国家杰出青年自然科学基金、孙冶方经济奖(中国经济学界最著名的奖项)等奖项的获得者。
发展中国家科学院(也称“世界科学院”) 原名为第三世界科学院, 简称为TWAS (The World Academy of Sciences),成立于1983年11月10日,总部设在意大利的里雅斯特,是非政府、非政治和非营利性的国际科学组织,由巴基斯坦物理学家、诺贝尔物理学奖获得者阿卜杜勒$\cdot$萨拉姆 (Abdus Salam) 教授倡议创建。

New Trends on the Mathematical Models and Solitons Arising in Real-World Problems
https://www.mdpi.com/journal/symmetry/special_issues/New_trends_mathematical_models_solitons_world_problems
The essence of mathematical tools for exemplifying the practical problems that exist in daily life is as old as the world itself. Mathematical models in science and technology have recently attracted an increased amount of researcher attentions with the aim to understand, describe, and predict the future behavior of natural phenomena. Recent studies on fractional calculus have been particularly popular among researchers due to their favorable properties when analyzing real-world models associated with properties such as anomalous diffusion, non-Markovian processes, random walk, long range, and most importantly heterogeneous behaviors. The concept of local differential operators along with power-law settings and non-local differential operators was suggested in order to accurately replicate the above-cited natural processes. The complexities of nature have led mathematicians and physicists to derive the most sophisticated and scientific mathematical operators to accurately replicate and capture pragmatic realities.
Mathematical physics plays a vital role in the study of the determinants and distribution of solitons. With the help of this, we can identify wave distributions in many fields of nonlinear sciences, and many experts have recently focused their work on this field. Further, these types of studies may help us to provide the foundation for developing public policy and make regulatory decisions relating to engineering problems, as well as to evaluate both existing and new perspectives. Major areas of mathematical physics studies with mathematical models include physics, symmetry, transmission, outbreak investigation, and epidemiological problems.
