text: This paper deals with dynamical optimal transport metrics defined by spatial
discretisation of the Benamou–Benamou formula for the Kantorovich metric . Such
metrics appear naturally in discretisations of -gradient flow formulations for
dissipative PDE. However, it has recently been shown that these metrics do not
in general converge to , unless strong geometric constraints are imposed on the
discrete mesh. In this paper we prove that, in a 1-dimensional periodic setting,
discrete transport metrics converge to a limiting transport metric with a non-trivial
effective mobility. This mobility depends sensitively on the geometry of the mesh
and on the non-local mobility at the discrete level. Our result quantifies to
what extent discrete transport can make use of microstructure in the mesh to reduce
the cost of transport.

text: We study the norm approximation to the Schrödinger dynamics of N bosons in
with an interaction potential of the form . Assuming that in the initial state
the particles outside of the condensate form a quasi-free state with finite kinetic
energy, we show that in the large N limit, the fluctuations around the condensate
can be effectively described using Bogoliubov approximation for all . The range
of β is expected to be optimal for this large class of initial states.
