Bernstein-type Theorems for constant mean curvature surfaces in the three-dimensional light cone

Shintaro Akamine, Wonjoo Lee, Seong-Deog Yang

We establish Bernstein-type theorems for entire constant mean curvature graphs in the three-dimensional light cone over the horosphere under the assumption that th…

Framed null curves and timelike surfaces via Lorentzian harmonic maps into de-Sitter 2-space

Shintaro Akamine, Hirotaka Kiyohara

We construct a class of Lorentzian harmonic maps into the de-Sitter -space satisfying the eigenvalue equation for the d'Alambert operator and a non-zero co…

Singularities on timelike minimal surfaces in Lorentzian Heisenberg group

Shintaro Akamine, Hirotaka Kiyohara

Timelike minimal surfaces in the three-dimensional Lorentzian Heisenberg group are shown to be constructed from Lorentzian harmonic maps into the de-Sitter two-sphere, and they nat…

Bernstein-type theorem for constant mean curvature surfaces in the isotropic 3-space

Shintaro Akamine, Wonjoo Lee, Seong-Deog Yang

There are many non-trivial entire spacelike graphs with constant mean curvature (CMC , for short) in the isotropic 3-space . In this paper, we show a value dis…

Singularities of generalized timelike minimal surfaces in Lorentz-Minkowski 3-space

Shintaro Akamine

A timelike minimal surface in Minkowski 3-space is a surface whose induced metric is Lorentzian and with vanishing mean curvature. Such surfaces have many kinds of singularities. I…

Isometric and anti-isometric classes of timelike minimal surfaces in Lorentz-Minkowski space

Shintaro Akamine

Isometric class of minimal surfaces in the Euclidean 3-space has the rigidity: if two simply connected minimal surfaces are isometric, then one of them is congruent…
