Before now in [2] the generalized Gaussian and mean curvatures were proved in Euclidean space, but now we prove the theorems in Lorentzian Space. In our previous paper, we have studied higher order Gaussian curvatures in Lorentzian space. This allowed us to prove that φ(P)= ∏_(i=1)^n▒(1+εi rki ) In addition to Gaussian and mean curvatures, K_r and H_r for parallel surfaces in E_1^3 are given. In this study by means of higher order Gaussian and mean curvatures we calculate the generalized curvatures K_r and H_r for parallel surfaces in E_1^(n+1).
