经典可积系统的现代方法
For many years, classical mechanics has been the driver of the development of various areas of mathematics. Currently, various applications such as robotics, cryptography, cryptocurrency, computer graphics, computer vision, and machine learning are actively influencing the development of algebraic geometry, differential geometry, Riemannian geometry, number theory, etc. The new tools obtained, or new computer implementations of the known tools, allow not only a new look at the classical integrable systems of the 18th-19th century, but also get a number of previously unknown results.
The goal of this course is to give students an overview of modern concepts and results in classical mechanics.
