Warped product semi-slant submanifolds of G.Q.S manifolds

Abstract

‎In this paper‎, ‎we characterize the warped product semi slant submanifolds $M:= M_{\theta}\times_f M_{\perp}$ and $M:= M_{T}\times_f M_{\theta}$ in a G.Q.S manifold and prove that every warped product semi-slant submanifold in the G.Q.S manifold $(\overline{M}‎, ‎\varphi‎, ‎\xi‎, ‎\eta‎, ‎g)$ is trivial‎.
