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…
