Semi-Parallel Tensor Product Surfaces In Semi-Euclidean Space E4 2

Abstract

In this article, the tensor product surfaces are studied that arisefrom taking the tensor product of a unit circle centered at the origin in Euclidean plane E2and a non-null, unit planar curve in Lorentzian plane E1. Also wehave shown that the tensor product surfaces in 4-dimensional semi-Euclideanspace with index 2; E4;satisfying the semi-parallelity condition R(X; Y ):h 0if and only if the tensor product surface is a totally geodesic surface in E4.
