Carlotto, Chodosh and Rubinstein studied the rate of convergence of the Yamabe flow on a closed (compact without boundary) manifold M:
∂∂tg(t)=−(Rg(t)−¯Rg(t))g(t)inM.
In this paper, we prove the corresponding results on manifolds with boundary. More precisely, given a compact manifold M with smooth boundary ∂M, we study the convergence rate of the Yamabe flow with boundary: ∂∂tg(t)=−(Rg(t)−¯Rg(t))g(t)inMandHg(t)=0on∂M
and the conformal mean curvature flow: ∂∂tg(t)=−(Hg(t)−¯Hg(t))g(t)on∂MandRg(t)=0inM.
