Math 226B:  Fukaya Categories
Fall 2023

Syllabus

Fukaya categories occupy a central role in modern mathematics, at the junction of algebraic geometry, symplectic geometry, low-dimensional topology, and mathematical physics.  The goal of this course is to give an introduction to Lagrangian Floer homology, Fukaya categories, and homological mirror symmetry.

  5. Exact triangles, twists, split generation
  6. Homological mirror symmetry e.g. of the torus
Prerequisites: Math 225 sequence or equivalent (a good knowledge of differentiable manifolds and homology).  Some knowledge of symplectic geometry is helpful, but not necessary.
