Complete explicit classification of parallel Lorentz surfaces in arbitrary pseudo-Euclidean spaces (Q988888)

A Lorentz surface of an indefinite space form is parallel if its second fundamental form is parallel. In the paper under review, the author obtains a complete explicit classification of parallel Lorentz surfaces in a pseudo-Euclidean space \(\mathbb{E}_{s}^{m}\) with arbitrary dimension \(m\) and arbitrary index \(s\).
