2020年9月6日，“未来科学大奖”获奖名单在北京揭晓。中国工业与应用数学学会第五、六届理事会副理事长，顾问委员会委员彭实戈院士因其在倒向随机微分方程理论，非线性Feynman-Kac公式和非线性数学期望理论中的开创性贡献，荣膺“数学与计算机科学奖”。

彭实戈院士和Pardoux合作于1990年发表的文章被认为是倒向随机微分方程理论（BSDE）的奠基性工作。这项工作开创了一个重要的研究领域，其中既有深刻的数学理论，又有在数学金融中的重要应用。彭实戈院士在这个领域一直持续工作，做出了一系列重要贡献。

彭实戈院士于1992年创建了非线性Feynman-Kac公式，从而对一大类二阶非线性微分方程给出了BSDE表示。

彭实戈院士发展了非线性数学期望的理论，这与传统的线性数学期望有本质上的不同，但相似的数学理论仍能够建立。这对风险的定义和定量有重大应用。

未来科学大奖是中国首个世界级民间科学大奖，由未来论坛于2016年创立，下设生命科学奖、物质科学奖、数学与计算机科学奖三个奖项，单项奖金为一百万美元（人民币约700万元）。强调奖励在大中华地区完成、产生巨大国际影响、具有原创性、长期重要性或经过了时间考验的科研工作，不论其国籍、性别和年龄，旨在推动突破性基础科学研究，表彰优秀科学家，吸引全球科技人才，促进科学事业发展。2016年至今，未来科学大奖共评选出20位获奖者，获得了科学和社会领域的广泛认可。

The 26th International Conference on Domain Decomposition Methods (DD26),  organized by the Chinese University of Hong Kong (CUHK), will now take place ONLINE from December 7 to 12, 2020. To take into account  the various geographical locations of our participants,  plenary talks are scheduled at a time that is reasonable for most time zones, and parallel sessions are scheduled twice a day in such a way that participants can attend at least one out of two sessions comfortably. Also, talks will be recorded for later viewing by other participants (subject to consent from individual speakers). The full schedule can be found on the conference website at the link below.

Registration is now open. The registration fees are HKD800 (about USD 100)  for regular participants, and HKD400 (about USD 50) for students. The deadline for registration is October 31, 2020. Participants who have previously registered and kept their fees for 2020 are automatically registered, and they will be contacted for refund arrangements.

We have reopened the call for minisymposia and contributed talks. Proposals should be in the form of a plain text e-mail to dd26@math.cuhk.edu.hk. For minisymposia, please provide a title, a short  description of the subject matter, and a list of speakers for the minisymposium. For contributed talks, please provide a title an abstract. The deadline for submitting proposals is October 15, 2020 (extended deadline). Previously accepted minisymposia and contributed talks are automatically accepted for this round.

Thanks to the generous support of the Hong Kong Peihua Education Foundation, we are now accepting applications for financial support, including registration fee, from graduate students, postdocs and junior faculty based in Mainland China. To be considered for funding, please email a cover letter, including a statement about why you want to participate, along with a CV to dd26@math.cuhk.edu.hk.  Deadline for submissions:  September 30, 2020.

• 摘要

We are looking for a postdoctoral computational scientist/applied mathematician to join the Chair of Computational Mathematics and Simulation Science, lead by Prof Jan S Hesthaven, to work in the area of scientific machine learning.

Current activities focus on the development of collaborative modes of interaction between modern computational methods and recent machine learning techniques, in particular based on neural networks. Such developments seek to overcome known algorithmic bottlenecks or enable entirely new ways of solving problems of relevance to science and engineering. The postdoctoral fellow is expected to engage in different projects in line with the above vision.

The ideal candidate will have the following skills: A PhD in mathematics, mechanical engineering or related topics; Experience with model order reduction techniques; Experience with modern computational methods for solving PDEs; Good programming skills.

The effort is of a collaborative nature so strong interpersonal and communication skills are required. Working language is English. There will  be some teaching responsibilities at EPFL as part of the  position.

We offer a 1 year contract with the possibility of an extension, a dynamic and inspiring working environment, and a competitive salary. A start date of January 1, 2021 is preferred but this is negotiable.

To express your interest, please send a letter of motivation, a resume, and at least 2 names of references to mcss@epfl.ch.  Evaluation of applications will begin late September and continue until the position is filled.
