Query: Simulation of Fractional Brownian Surfaces via Spectral Synthesis on
  Manifolds   Using the spectral decomposition of the Laplace-Beltrami operator we simulate
fractal surfaces as random series of eigenfunctions. This approach allows us to
generate random fields over smooth manifolds of arbitrary dimension,
generalizing previous work with fractional Brownian motion with
multi-dimensional parameter. We give examples of surfaces with and without
boundary and discuss implementation.
