Query: Quenched Invariance Principle for a Reflecting Diffusion in a Continuum
  Percolation Cluster   We consider a continuum percolation built over stationary ergodic point
processes. Assuming that the occupied region has a unique unbounded cluster and
the cluster satisfies volume regularity and isoperimetric condition, we prove a
quenched invariance principle for reflecting diffusions on the cluster.
