Semi-parallel tensor product surfaces in semi-Euclidean space E24

In this article, the tensor product surfaces are studied that arise from taking the tensor product of a unit circle centered at the origin in Euclidean plane E-2 and a non-null, unit planar curve in Lorentzian plane E-1(2). Also we have shown that the tensor product surfaces in 4-dimensional semi-Euclidean space with index 2, E-2(4), satisfying the ...

Classification of marginally trapped Lorentzian flat surfaces in E24 and its application to biharmonic surfaces

Journal of Mathematical Analysis and Applications
AbstractA surface in a semi-Riemannian manifold is called marginally trapped if its mean curvature vector field is light-like at each point. In this article, we classify marginally trapped Lorentzian flat surfaces in the pseudo-Euclidean space E24. As an application, we obtain the complete classification of biharmonic Lorentzian surfaces in E24 with ...
