Null 2-type space-like submanifolds of $$E_t^5$$ with normalized parallel mean curvature vector. (English) Zbl 1113.53010
Summary: The purpose of this article is to classify 3-dimensional null 2-type space-like submanifolds of the pseudo-Eulidean space $$E^5_t$$ which are constructed from the eigenfunctions of the Laplacian with two eigenvalues 0 and nonzero constant $$\lambda$$, under certain assumptions.
