A flow approach to the generalized Loewner-Nirenberg problem of the ${\sigma }_k$-Ricci equation

Abstract

We introduce a flow approach to the generalized Loewner-Nirenberg problem $(1.5)-(1.7)$ of the ${\sigma }_k$-Ricci equation on a compact manifold $(M^n,g)$ with boundary. We prove that for initial data $u_0\in C^{4,\alpha }(M)$ which is a subsolution to the ${\sigma }_k$-Ricci equation $(1.5)$, the Cauchy-Dirichlet problem $(3.1)-(3.3)$ has a unique solution $u$ which converges in $C_{loc}^4(M^{\circ })$ to the solution $u_{\infty }$ of the problem $(1.5)-(1.7)$, as $t\to \infty$.
