Warped Product Contact Cr-Submanifolds of Trans-Sasakian Manifolds

K. A. Khan, V. A. Khan, Sirajuddin

B. Y. Chen [4] showed that there exists no proper warped CR-submanifolds $N_\bot\times_fN_T$ of a Kaehler manifold and obtained many results on CR-warped products $N_T\times_fN_\bot$. Contact CR-warped product submanifolds in Sasakian manifold were studied by I. Hasegawa and I. Mihai [6]. In this paper we have investigated the existence of contact CR-warped product submanifolds in more general setting of trans-Sasakian manifolds.
