In this paper, our purpose is to obtain uniqueness results related to the mean curvature equation for entire Killing graphs constructed over the base of a warped product of the type with warping function ρ and density f. For this, we establish a suitable f-parabolicity criterion and, under appropriate constraints on the Bakry-Émery-Ricci tensor and on the f-mean curvature, we prove some rigidity results concerning two-sided hypersurfaces immersed in .

在本文中,我们的目的是获得与在基上构造的整个Killing图的平均曲率方程有关的唯一性结果 类型的翘曲产品 具有翘曲函数ρ和密度f。为此,我们建立了一个合适的f抛物线准则,并且在Bakry-Émery-Ricci张量和f-平均曲率的适当约束下,我们证明了浸入其中的两面超曲面的一些刚度结果。
