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.eninfo:eu-repo/semantics/openAccessFizikMatematikArticle652133141209736
