Constant-curvature convergence conjecture for normalized Ricci flow on trees

About 1 year old · traced to

Let T=(V,E)T=(V,E) be a tree with an initial metric w∈R>0Ew\in\mathbb{R}_{>0}^{E}, and let the metric w(t)w(t) evolve under the normalized Ricci flow. The flow converges to a metric with constant curvature if there exists a metric w(∞)∈R≥0Ew(\infty)\in\mathbb{R}_{\geq 0}^{E} such that

lim⁡t→∞w(t)=w(∞)\lim_{t\to\infty}w(t)=w(\infty)

and, writing E+={e∈E(T):we(∞)>0}E^{+}=\{e\in E(T):w_e(\infty)>0\}, the curvature under w(∞)w(\infty) is the same on every edge in E+E^{+}. Constant-curvature convergence conjecture. For every tree with an initial metric, the normalized Ricci flow converges to a metric with constant curvature. This conjecture proposes a global asymptotic property of normalized Ricci flow on trees; the supplied source does not establish whether it is known or remains open.
