Constant angle surfaces in Lorentzian Berger spheres
Irene I. Onnis, Apoena Passos Passamani, Paola Piu
In this work, we study helix spacelike and timelike surfaces in the Lorentzian Berger sphere $\s_{\varepsilon}^3$, that is the three-dimensional sphere endowed with a -parameter…

Enneper representation of minimal surfaces in the three-dimensional Lorentz-Minkowski space
Irene I. Onnis, Adriana A. Cintra
In this paper, we will give an Enneper-type representation for spacelike and timelike minimal surfaces in the Lorentz-Minkowski space , using the complex and the paracomplex…

Constant angle surfaces in the Lorentzian Heisenberg group
Irene I. Onnis, P. Piu
In this paper, we define and, then, we characterize constant angle spacelike and timelike surfaces in the three-dimensional Heisenberg group, equipped with a 1-parameter family of…
