摘要：
We investigate necessary and sufficient conditions for the extendibility and boundedness of Gaussian curvature, mean curvature and principal curvatures near all types of singularities on fronts. We also study the divergence to infinity of these geometrical invariants near singularities and show how this is tightly related to a particular property of uniform approximation of fronts by parallel regular surfaces.
