Heat flow method to Lichnerowicz type equation on closed manifolds

Li Ma, Yuhua Sun

摘要:

本文在闭流形中建立了如下类型的Lichnerowicz方程-Δu=A(x)u^{-p}-B(x)u^{q},\quad在\quad M中正解的存在性结果,其中$p>1, q>0$,$A(x)>0$,$B(x)\geq0$是光滑函数.我们的分析是基于以下热方程{ll} u_t-Δu=A(x)u^{-p}-B(x)u^{q},\quad在\quad M中\times \mathbb{R}^{+},u(x,0)=u_0,\quad在\quad M中,具有正光滑初始值$u_0$的整体正解的存在性.

英文摘要:

In this paper, we establish existence results for positive solutions to the Lichnerowicz equation of the following type in closed manifolds -Δu=A(x)u^{-p}-B(x)u^{q},\quad in\quad M, where $p>1, q>0$, and $A(x)>0$, $B(x)\geq0$ are given smooth functions. Our analysis is based on the global existence of positive solutions to the following heat equation {ll} u_t-Δu=A(x)u^{-p}-B(x)u^{q},\quad in\quad M\times\mathbb{R}^{+}, u(x,0)=u_0,\quad in\quad M with the positive smooth initial data $u_0$.
