Topics in Arithmetic Dynamics

Seminar in Number Theory, 18.784, Spring 2025

Syllabus

Welcome to 18.784: Seminar in Number Theory! This course is a Communication Intensive in Mathematics (CI-M) for undergraduates at MIT.

This semester, we will explore arithmetic dynamics — an area of mathematics that studies how numbers move. The subject lies at the intersection of dynamical systems and number theory, involving a breadth of mathematical disciplines including:

  • Algebraic geometry
  • Algebraic number theory
  • Algorithmic number theory
  • Analytic number theory
  • Combinatorics
  • Complex analysis
  • p-adic analysis
  • Representation theory

Students will prepare a short paper and present specific topics in arithmetic dynamics. Grading is primarily based on the paper, presentations, and active participation during the semester.

Prerequisites for the course are Algebra 1 (18.701) or (Modern Algebra (18.703) and Linear Algebra (18.06 or 18.700)).
Additional mathematical background, such as elementary number theory (18.781) and Galois theory (18.702), will be helpful but not required.

The seminar meets in 2-151 from 1:00pm—2:30pm (ET) on Tuesdays and Thursdays.
