On the Curvatures of (k+1)-Dimensional Semi-Ruled Surfaces in \({{E}_{v}^{n+1} }\)

In this paper, first we will define the generalized (k + 1) -dimensional semi-ruled surface M*, such that the generator space of M* is the semi-subspace of $E_v^{n+1}$ where $E_v^{n+1}$ is the semi-Euclidean space. Then, we will compute the mean curvature, Riemann curvature, Ricci curvature and scalar curvature of M*.
