【 摘 要 】

In this paper, we study the Einstein warped products and multiply warped products with a quarter-symmetric connection. We also study warped products and multiply warped products with a quarter-symmetric connection with constant scalar curvature. Then we apply our results to generalized Robertson Walker space times with a quarter-symmetric connection and generalized Kasner space times with a quarter-symmetric connection.
