             Abstract
    Riemannian manifold Hamiltonian Monte Carlo
    is traditionally carried out using the generalized
    leapfrog integrator. However, this integrator is
    not the only choice and other integrators yield-
    ing valid Markov chain transition operators may
    be considered. In this work, we examine the i ...
