Sharp hypocoercive convergence estimates for underdamped Langevin dynamics with specular reflection
Hengrong Du, Qi Feng, Lingjiong Zhu
We study the underdamped (kinetic) Langevin dynamics confined to a bounded convex domain by specular reflection of the velocity at the boundary. This process…

Non-Reversible Langevin Algorithms for Constrained Sampling
Hengrong Du, Qi Feng, Changwei Tu +2
We consider the constrained sampling problem where the goal is to sample from a target distribution on a constrained domain. We propose skew-reflected non-reversible Langevin dynam…
