**Introduction to Symplectic Geometry**

(MWF 9:30-10:20 @ 200-303)

Office hours: W, 4-5pm

**Grades and homework:**

Bi-weekly homeworks will be posted here. Grade is entirely based on homework.

Problem set 1 (due Oct 4) Solution to q4 (by Dylan)

**Plan for the course:**

- The first 8 lectures of "Lectures on Symplectic Manifolds", by Alan Weinstein

- Gromov non-squeezing theorem (possibly from Gromov's original paper, cited below)

- Symplectic rigidity of Lagrangian submanifolds (from Audin-Lalonde-Polterovich article cited below)
