Mixed type surfaces with bounded Gaussian curvature in three-dimensional Lorentzian manifolds
Atsufumi Honda, Kentaro Saji, Keisuke Teramoto
A mixed type surface is a connected regular surface in a Lorentzian 3-manifold with non-empty spacelike and timelike point sets. The induced metric of a mixed type surface is a sig…

Dualities of differential geometric invariants on cuspidal edges on flat fronts in the hyperbolic space and the de Sitter space
Kentaro Saji, Keisuke Teramoto
We compute the differential geometric invariants of cuspidal edges on flat surfaces in hyperbolic -space and in de Sitter space. Several dualities of invariants are pointed out.

Singularities of a surface given by Kenmotsu-type formula in Euclidean three-space
Luciana F. Martins, Kentaro Saji, Keisuke Teramoto
We study singularities of surfaces which are given by Kenmotsu-type formula with prescribed unbounded mean curvature.
