   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.},

   Title = {Ergodic Properties of Quasi-Markovian Generalized Langevin

             Non-conservative Force},

   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.},
