Submanifolds satisfying some curvature conditions imposed on the Weyl tensor

In this paper we define Weyl semiparallel ( · h = 0) and Weyl 2-semiparallel ( · ∇̅h = 0) submanifolds. We consider n-dimensional normally flat submanifolds satisfying these curvature conditions in (n + d)-dimensional Euclidean space n+d. We also consider normally flat submanifolds in (n + d)-dimensional Euclidean space n+d satisfying the condition  · h = LQ (g, h) and  · ∇̅h = LQ(g, ∇̅h).
