35. HMC on Riemannian Manifolds

Anthony Kennedy

8/16/22, 8:45 AM

I shall give a pedagogical introduction to the Hamiltonian/Hybrid Monte Carlo algorithm (HMC) on Riemannian manifolds. I will explain how Hamiltonian systems are most naturally formulated in terms of Hamiltonian vector fields $\hat X$ on symplectic manifolds: the relationship between commutators of Hamiltonian vector fields and Poisson brackets, $[\hat X,\hat Y] = \widehat{\{X,Y\}}$; why a...
