Query: On a global estimate of the Diederich--Fornaess index of Levi-flat real
  hypersurfaces   In this expository paper, we review a recent progress of the study of the
Diederich--Fornaess index of complex domains with emphasis on the case of
domains with Levi-flat boundary. It is exhibited that for any compact Levi-flat
real hypersurface, the norm of its infinitesimal holonomy must exceed the
curvature of its normal bundle at a point.
