      abstract     = {As a first step toward the interpretation of dynamic light
                      scattering with evanescent illumination from suspensions of
                      interacting spheres, in order to probe their near wall
                      dynamics, we develop a theory for the initial slope of the
                      intensity autocorrelation function. An expression for the
                      first cumulant is derived that is valid for arbitrary
                      concentrations, which generalizes a well-known expression
                      for the short-time, wave-vector dependent collective
                      diffusion coefficient in bulk to the case where a wall is
                      present. Explicit expressions and numerical results for the
                      various contributions to the initial slope are obtained
                      within a leading order virial expansion. The dependence of
                      the initial slope on the components of the wave vector
                      parallel and perpendicular to the wall, as well as the
                      dependence on the evanescent-light penetration depth are
                      discussed. For the hydrodynamic interactions between
                      colloids and between the wall, which are essential for a
                      correct description of the near-interface dynamics, we
                      include both far-field and lubrication contributions.
                      Lubrication contributions are essential to capture the
                      dynamics as probed in experiments with small penetration
                      depths. Simulations have been performed to verify the theory
                      and to estimate the extent of the concentration range where
                      the virial expansion is valid. The computer algorithm
                      developed for this purpose will also be of future importance
                      for the interpretation of experiments and to develop an
                      understanding of near-interface dynamics, at high colloid
                      concentrations.},
