We planned this paper into two main sections. In the first section, we gjve an analog for the Lorentzian case of some characterizations given in [2 ]. There is no difference between the characterizations in both cases of inunersions with (pointwise) 2-planar normal sections of Riemannian and Lorentzian manifolds into R™ and R,”*, respectively, but the ptoofs.
In the second part of paper, we deal with the Tlıeorem. 3.2 given in [1 ] and show that there must be some extra hypothesis to get the characterizations given as Theorems 2.1 and 2.2 in the present paper.
