Abstract. In this paper we get some rigid results for m−dimensional quasiEinstein metrics on complete Riemannian manifolds.

In this paper, we will study the τ -quasi-Einstein metrics on complete noncompact Riemannian manifolds and get a rigid property. We will also obtain lower and upper estimates for scalar curvatures on these metrics by using the maximum principle.

Preoperative SCR significantly reflected the surgical outcome in patients with CSM. Patients with SCR greater than or equal to 1.46 can experience poor recovery after surgery.
