Quantization and Cohomology (Week 5)
Posted by John Baez
Still catching up… here are the notes for the Halloween class on Quantization and Cohomology:
-
Week 5 (Oct. 31) -
The canonical 1-form on . Symplectic structures. Why a symplectic structure should be a nondegenerate 2-form (so we get time evolution from a Hamiltonian) and closed (so time evolution preserves this 2-form). The action expressed in terms of the canonical 1-form.
-
Homework: show that if is the canonical 1-form on the
cotangent bundle of a manifold, then
is a nondegenerate 2-form.
Last week’s notes are
here; next week’s notes are
here.

That Shift in Dimension
Weblog: The n-Category Café
Excerpt: What makes the Kontsevich-Cattaneo-Felder theorem tick? How can it be that an n-dimensional quantum field theory is encoded in an (n+1)-dimensional one?
