Geometry of $CRS$ bi-warped product submanifolds in Sasakian and cosymplectic manifolds

Bang-Yen Chen, Siraj Uddin, Azeb Alghanemi +2

In this paper, we prove that there are no proper $CRS$ bi-warped product submanifolds other than contact CR-biwarped products in Sasakian manifolds. On the other hand, we prove tha…
