Week 1. 7/25-7/29
Group discussion: 7/30-7/31 10:00-14:00
Title:
Introductory and Arithmetic aspects
Lecturer:
Prof. Yi-Fan Yang (NCTU)
Abtract:
The first week serves as an introductory to elliptic curves together with some basic number theoretical discussion. It is consists of the following four parts.
-
Elliptic curves over C: elliptic functions, Weierstrass equation, Weierstrass P-function, addition law, modular curve as the moduli space of elliptic curves, and classification of endomorphism rings of elliptic curves over C.
-
Elliptic curves over Q: points of finite order on elliptic curves (the Nagell-Lutz theorem), and the Mordell theorem.
-
Elliptic curves over finite fields: Hasse's theorem, application to integer factorization (Lenstra's algorithm) and cryptography.
-
L-functions of elliptic curves over Q.

Week 2. 8/1-8/5
Group discussion: 8/6-8/7 10:00-14:00
Title:
Algebraic aspects : Dualities of Elliptic Curves
Lecturer:
Prof. Wu-Yen Chuang (NTU/NCTS)
Abstract:
We will first introduce the line bundles on complex tori, Poincare line bundle, cohomology of the line bundles, and theta functions. After introducing the basics, I will talk about the homological mirror symmetry for elliptic curves to show how the basics are put into use.

Week 3. 8/8-8/12
Group discussion: 8/13 10:00-12:00
Title:
An introduction to complex analytic geometry: Bergman kernel and Demailly's Morse inequalities
Lecturer:
Prof. Chin-Yu Hsiao (AS/NCTS)
Abstract:
An elliptic curve over C is a Riemann surface and is isomorphic as a complex torus. Theta functions are holomorphic functions on C g , quasi-periodic with respect to a lattice. From modern point of view, elliptic curve over C is an 1-dimensional complex manifold and Theta functions are sections of line bundles on complex torus. Complex geometry is the study of complex manifolds (Elliptic curve over C) and the behavior of holomorphic sections (Theta functions). Demailly’s Morse inequalities and Bergman kernel are powerful tool to study the behavior of holomorphic sections. In this course, I will give a Bergman kernel proof of Demailly’s Morse inequalities. In the proof, we only need undergraduate P.D.E and basic complex analysis. We will not assume any background knowledge of complex geometry.
