授業の目的　【日本語】
Goals of the Course(JPN)

The purpose of this course is to introduce and explain various concepts and methods in mathematical sciences. This year, the course is provided by three instructors.

Part I (Ryoichi Kobayashi) Douglas's solution to the Plateau Problem asserts that there exists a surface spanning a given counter with least area. This lecture is an account of this result.

Part II (Tetsuya Shiromizu) General relativity is based on the Riemann geometry. One can learn that it describes our universe and black hole.

Part III (Johannes Jaerisch). We give an introduction to the mathematical concept of entropy, which plays an important role in statistical physics, information theory, and dynamical systems.

到達目標　【日本語】
Objectives of the Course(JPN))

Part I (Ryoichi Kobayashi) My goal of this lecture is to give a self-contained account of Douglas's solution to the classical Plateau problem. I hope this lecture will be a reasonable introduction to modern geometric analysis.

Part II (Tetsuya Shiromizu) enjoying the Riemann geometry and partial differential equation through the theory for spacetime.

Part III (Johannes Jaerisch) To give an introduction to the mathematical concept of entropy, and some of its applications.

授業の内容や構成
Course Content / Plan

Part I (Ryoichi Kobayashi) Self-contained account on Douglas's solution to the Plateau Problem. ① What is minimal surface ? ② Harmonic function and Dirichlet problem.
③ Dirichlet's principle. Douglas's solution to the Plateau problem.

Part II: General relativity (Tetsuya Shiromizu)

In this part of the lecture, we give the brief introduction of the Riemann geometry and then formulate general relativity which is the theory for spacetime. As a consequence, we can discuss black hole and expanding universe in terms of the Riemann geometry.

Part III: Entropy (Johannes Jaerisch)

We give an introduction to the mathematical concept of entropy, which plays an important role in statistical physics, information theory, and dynamical systems. We discuss the theorem of Shannon-McMillan-Breiman theorem and the asymptotic equipartition property, as well the role of entropy in the classification of measure-preserving dynamical systems.
