Query: Singularities of Gauss maps of wave fronts with non-degenerate singular
  points   We study singularities of Gauss maps of fronts and give characterizations of
types of singularities of Gauss maps by geometric properties of fronts which
are related to behavior of bounded principal curvatures. Moreover, we
investigate relation between a kind of boundedness of Gaussian curvatures near
cuspidal edges and types of singularities of Gauss maps of cuspidal edges.
Further, we consider extended height functions on fronts with non-degenerate
singular points.
