Arithmetic of Plane CurvesHHU Düsseldorf, Wintersemester 2026/27 Teacher: Jun.-Prof. Dr. Marta Pieropan
Lecture room: 2522.00.72
ContentPlane curves are subsets of the projective plane defined by homogeneous polynomials in three variables. In this course you will study the set of solutions of those homogeneous polynomials over fields that are not algebraically closed and learn about their properties. Learning objectives:
In degree 2, you will learn about plane conics, their classification un to isomorphism and their connection to quaternion algebras. In degree 3, you will learn about elliptic curves, their group of points, the Mordell-Weil Theorem over the rational numbers, and the structure of the group of torsion points. In degree at least 4, you will learn about Fermat's descent and its application to prove some cases of Fermat's Last Theorem. Time permitting, we will get a glimpse about the theory behind Wile's proof of Fermat's Last Theorem.
Exercise classesThe schedule for the exercise sessions will be agreed upon during the first lecture. Further information about the exercise sessions will appear later. ExamAdmittance to the final exam will be based on oral presentations of homework during the exercise session. More information will be given during the first lecture. Further information about the exam will appear later.
