Elliptic curves
(Nagoya University, Spring 2024)
We will meet for the first time on April 12th in Room 453 of the math building. Please make sure that you will be part of this TACT group. If you want to audit this lecture please contact me so I can add you to it.

Content (Tentative):
この講義では楕円曲線の入門的内容を取り扱います。この講義は英語で行われます。予備知識としては、代数学の講義で取り扱われる内容を仮定します。受講学生の多くは日本語で行われた代数学の講義を受講していると思いますが、本講義の最初に代数学の知識の復習を行うことで、学生が代数学における英語の語彙を学ぶことができるようにします。
Elliptic curves are central to both modern mathematics and practical applications like cryptography. In arithmetic geometry, they've been instrumental in significant breakthroughs, such as Andrew Wiles' proof of Fermat's Last Theorem. The lecture series will cover the basic theory of elliptic curves, potentially extending to advanced topics based on audience interest. We start with elliptic curves over the complex numbers, seen as quotients of the complex plane by a lattice, an approach that merges complex analysis with algebraic descriptions as cubic polynomials define these curves. Moving to algebraic geometry, we explore elliptic curves over various fields, highlighting their role as simple examples of abelian varieties - projective varieties with a group structure. Discussions will span theories over finite fields and number fields, integrating concepts from complex analysis, algebraic geometry, number theory, and their crucial use in cryptography. A detailed overview will come in March.
