摘要

受fisher - marsden(杜克数学)的启发。[j] . 42(1975)， 519-547]，本文研究了加权标量曲率的变形。通过研究加权标量曲率线性化的形式$L_\phi^2$伴随的核，证明了几个几何结果。特别地，我们定义了一个加权真空静态空间，并研究了局部共形平坦加权真空静态空间。然后证明了平面空间上加权标量曲率的一些稳定性结果。最后，我们考虑了闭光滑度量测度空间上的规定加权标量曲率问题。

Deformation of the Weighted Scalar Curvature

Inspired by the work of Fischer-Marsden [Duke Math. J. 42 (1975), 519-547], we study in this paper the deformation of the weighted scalar curvature. By studying the kernel of the formal $L_\phi^2$-adjoint for the linearization of the weighted scalar curvature, we prove several geometric results. In particular, we define a weighted vacuum static space, and study locally conformally flat weighted vacuum static spaces. We then prove some stability results of the weighted scalar curvature on flat spaces. Finally, we consider the prescribed weighted scalar curvature problem on closed smooth metric measure spaces.
