北京大学副校长、中国工业与应用数学学会理事长张平文院士，北京大学副教授、中国工业与应用数学学会副秘书长张磊老师，浙江大学副教授王伟老师在数学领域排名第一的期刊Acta Numerica上发表了前沿文章：Modelling and computation of liquid crystals。
液晶是一种介于液体和晶体之间的软物质。过去四十年液晶的研究取得了巨大的进展，不仅极大地促进了基础科学研究，同时在工业上得到了广泛的应用。论文讨论了液晶三类不同层次的数学模型，从严格数学意义上或形式上建立不同模型之间联系；综述了液晶的计算方法，并列举了各类受限在不同几何区域和条件下向列相液晶的缺陷构型；介绍了近年来提出的解景观方法，给出了受限区域内向列相液晶完整的解景观。论文指出液晶的科学价值不仅在于提出新的数学问题，而且极大促进了新的研究方法，同时对液晶的未来研究提出了一些展望。

2019年11月26日联合国教科文组织第四十届大会上正式宣布的将每年的3月14日定为“国际数学日”。该项目由国际数学联盟（IMU）发起，每年确定一个主题，并号召全球在3月14日围绕主题组织各项活动。在刚刚过去的2022年第三届国际数学日，全球超过90个国家围绕“Mathematics Unites（万物皆数）”主题举办了丰富的庆祝活动。
2023年国际数学日筹备工作已启动。中国数学会现面向全国征集2023年国际数学日主题。如果您有好的想法，请将您心中的主题建议及其理由以邮件形式发送到中国数学会邮箱（cms@math.ac.cn）。经过遴选后，优秀的主题建议将由中国数学会帮您提交到国际数学联盟（IMU）。此次全国征集的截止是2022年5月10日。
期待您的参与！
中国数学会
2022年4月9日
过去三届国际数学日主题：
2020年：“Mathematics is Everywhere”（数学无处不在）
2021年：“Mathematics for a Better World”（数学让世界更美好）
2022年：“Mathematics Unites”（万物皆数）
国际数学联盟（IMU）是2022年可持续发展基础科学国际年(IYBSSD 2022)的创始伙伴之一，国际数学日主题可考虑与IYBSSD 2022相关的。
