现代变分分析是数学领域的重要研究课题之一，它主要研究在各种约束优化以及优化相关问题对于扰动的灵敏性和稳定性。现代变分分析已广泛应用于运筹优化、最优控制、动力系统、机器学习与通信等领域，并在优化理论与算法分析中起着基础性作用。近年来，国内外许多著名学者在该领域辛勤耕耘，促使现代变分分析与优化理论发展日新月异，一阶变分分析理论日益完善，二阶变分分析正蓬勃发展。二阶或高阶变分分析理论为分析设计高效可行算法提供了重要的工具，它完全有可能解决人工智能等发展面临的“卡脖子”窘境--核心算法缺位问题。相对国外在现代变分分析与优化方法方面的研究而言，我国在该领域研究还不够，特别是二阶或高阶变分分析研究方面还处于起步阶段。为进一步助力我国学者在现代变分分析与优化理论及其相关问题上的研究与应用水平，我们拟于2022年7月在西南大学为国内青年学者举办为期3周的现代变分分析与数学优化专题高级讲习班。

Modern variational analysis is one of the important research topics in the field of mathematics, which mainly studies the sensitivity and stability of constrained optimization and its related problems with respect to the disturbances. Modern variational analysis has been widely used in the fields of operation research, optimal control, dynamic system, machine learning, and communication, and plays a fundamental role in optimization theory and algorithm analysis. In recent years, many famous scholars have been working hard in this field, which promotes the development of modern variational analysis and optimization theory, the theory of first-order variational analysis is increasingly perfect, and the second-order variational analysis is booming. Second order or higher-order variational analysis theory provides an important tool for the analysis and design of efficient and feasible algorithms. It is entirely possible to solve the "neck" dilemma faced by the development of artificial intelligence, such as the lack of core algorithms. Compared with the foreign research on modern variational analysis and optimization methods, the research in this field in China is not enough, especially the research on second-order or higher-order variational analysis is still in its infancy. In order to improve the relevant research and applications, we plan to hold a 3-weeks’ symposium on modern variational analysis and optimization for young scholars, in July 2022, in Southwest University.
