Space-time divergence lemmas and optimal non-reversible lifts of diffusions on Riemannian manifolds with boundary
Andreas Eberle, Francis Lörler
Non-reversible lifts reduce the relaxation time of reversible diffusions at most by a square root. For reversible diffusions on domains in Euclidean space, or, more generally, on a…

Non-reversible lifts of reversible diffusion processes and relaxation times
Andreas Eberle, Francis Lörler
We propose a new concept of lifts of reversible diffusion processes and show that various well-known non-reversible Markov processes arising in applications are lifts in this sense…
