Abstract = {© 2019, Springer Science+Business Media, LLC, part of
Springer Nature. We discuss the classical problem of how to
pick N weighted points on a d-dimensional manifold so as to
obtain a reasonable quadrature rule 1|M|∫Mf(x)dx≃∑n=1Naif(xi).This
problem, naturally, has a long history; the purpose of our
paper is to propose selecting points and weights so as to
minimize the energy functional ∑i,j=1Naiajexp(-d(xi,xj)24t)→min,wheret∼N-2/d,d(x, y)
is the geodesic distance, and d is the dimension of the
manifold. This yields point sets that are theoretically
guaranteed, via spectral theoretic properties of the
Laplacian - Δ , to have good properties. One nice aspect is
that the energy functional is universal and independent of
the underlying manifold; we show several numerical
examples.},

Abstract = {We discuss the ergodic properties of quasi-Markovian
stochastic differential equations, providing general
conditions that ensure existence and uniqueness of a smooth
invariant distribution and exponential convergence of the
evolution operator in suitably weighted $$L^\infty $$spaces,
which implies the validity of central limit theorem for the
respective solution processes. The main new result is an
ergodicity condition for the generalized Langevin equation
with configuration-dependent noise and (non-)conservative
force.},
