英文摘要
Properties of certain classes of surfaces with singularities are investigated with Weirstrass-type representation formula. For example, global behavior of flat fronts, and behavior of singularities of maximal surfaces in Lorentz-Minkowski 3-space and mean curvature one surfaces in de Sitter 3-space are investigated.On the other hand, as a general theory of differential geometry of singularities, a notion of singular curvature of the singular points of wave fronts is defined, and Gauss-Bonnet type formulas are obtained.
