### Quantization and Cohomology (Week 3)

#### Posted by John Baez

Sorry for the long pause! Here are the notes for the October 17th class on Quantization and Cohomology:

- Week 3 (Oct. 17) - From Lagrangian to Hamiltonian dynamics. Momentum as a cotangent vector. The Legendre transform. The Hamiltonian. Hamilton’s equations.

Last week’s notes are here; next week’s notes are here.

The Legendre transform cropped up in my last post too. You don’t happen to have one of those lovely little phrases which can help me see what all uses of the transform have in common, and further what the Legendre transform has in common with the Laplace transform so that they’re only a change of rig away.
