Minimal Darboux transformations

U. Hertrich-Jeromin, A. Honda

We derive a permutability theorem for the Christoffel, Goursat and Darboux transformations of isothermic surfaces. As a consequence we obtain a simple proof of a relation between D…

Fold singularities on spacelike CMC surfaces in Lorentz-Minkowski space

Atsufumi Honda, Miyuki Koiso, Kentaro Saji

Fold singular points play important roles in the theory of maximal surfaces. For example, if a maximal surface admits fold singular points, it can be extended to a timelike minimal…

Isometric immersions with singularities between space forms of the same positive curvature

Atsufumi Honda

In this paper, we give a definition of coherent tangent bundles of space form type, which is a generalized notion of space forms. Then, we classify their realizations in the sphere…

The lightlike geometry of marginally trapped surfaces in Minkowski space-time

Atsufumi Honda, Shyuichi Izumiya

The lightlike geometry of codimension two spacelike submanifolds in Lorentz-Minkowski space has been developed in [Izumiya, S. and Romero Fuster, M. C. Selecta Mathematica (NS), 13…

Intrinsic properties of surfaces with singularities

Masaru Hasegawa, Atsufumi Honda, Kosuke Naokawa +3

In this paper, we give two classes of positive semi-definite metrics on 2-manifolds. The one is called a class of Kossowski metrics and the other is called a class of Whitney metri…
