Convergence of the Weighted Yamabe Flow

Differential Geometry 2023-04-17 v2

Abstract

We introduce the weighted Yamabe flow gt=(rϕmRϕm)g\frac{\partial g}{\partial t}=(r^m_{\phi}-R^m_{\phi})g, ϕt=m2(Rϕmrϕm)\frac{\partial \phi}{\partial t}=\frac{m}{2}(R^m_{\phi}-r^m_{\phi}) on a smooth metric measure space (Mn,g,eϕdvolg,m)(M^n, g, e^{-\phi}{\rm dvol}_g, m), where RϕmR^m_{\phi} denotes the associated weighted scalar curvature, and rϕmr^m_{\phi} denotes the mean value of the weighted scalar curvature. We prove long-time existence and convergence of the weighted Yamabe flow if the dimension nn satisfies n3n\geqslant 3.
