An introduction to complex differential geometry
 
任课老师(instructor): 张希(Zhang Xi)
1, 课程大纲(Syllabus)
 
   There has been fundamental progress in complex differential geometry in the last three decades, non-linear analysis method have been found very useful in the study of complex differential geometry.  The aim of this course is to give an essentially self-contained introduction to the basic theories, concepts of complex differential geometry, and present the students with some advanced topics in Kaehler geometry specially in the theory of canonical metrics and nonlinear PDE on complex manifolds. This course include three topics. The first topic include the basic theories, concepts of complex geometry and Kaehler geometry, for example: almost complex structure, complex manifold, Chern class, holomorphic vector bundle, Hermitian and Kaehleian structure, the curvature of Kaehler metric, Hodge theory. The second topic will focus on  Calabi-Yau theorem and complex Monge-Ampere equation. In the lastly topic, we introduce the  Hermitian-Einstein equation and its applications.
This course shoud be suitable for senior undergraduates and graduated students with a basic knowledge in complex anlaysis, PDE and differential manifold.

An invitation to algebraic geometry.

任课老师(instructor): Alessandro Chiodo

 

Schedule. 4,6,7,8,9,13,14/7/2020 (seven 1h30 lectures starting from 3pm to 4:30 pm Hangzhou time)

Lecture 1 - 4/7 - The genus of a curve.

Lecture 3 - 6/7 - Riemann-Roch

Lecture 4 - 7/7 - Serre duality

Lecture 5 - 8/7 - The canonical map

Lecture 6 - 9/7 - Riemann-Hurwitz

Lecture 7 - 13/7 - Abel theorem

Lecture 7 - 14/7 - Final comments

 

Abstract: The course introduces some of the main theorems of algebraic geometry in the case of smooth complex curves. The plan is to gradually move from the simplest objects to the study of maps between them, and prepare the students to a future systematic study of singular and higher dimensional objects. The lectures may be also attended to simply get a gist of the subject. We provide simple proofs of these theorems based on the knowledge of an undergraduate student in his third year: we essentially rely on some knowledge of complex differential forms, which we will systematically recall and recast in our context.

 

Introduction to Ergodic Theory

任课老师(instructor): 陈国璋 (Chen, Kuo-Chang)

 

Abstract:

Ergodic theory is the mathematical subject which studies long-term

average behavior of measurable dynamical systems. It has deep

connections with statistical physics, functional analysis, number

theory, probability, differential geometry, among others. This short

course is a brief introduction intended for students who are interested

in dynamical systems and analysis. Audiences are assumed to have some

basic knowledge in real analysis.

 

Schedule:

There will be 5 lectures, 3 hours for each lecture:

Lecture 1. Invariant and ergodic measures

Lecture 2. Ergodic theorems

Lecture 3. Mixing properties

Lecture 4. Recurrence

Lecture 5. Entropy
