Lemma 3.4.

There is a fixed number δ1>0\delta_{1}>0, such that for s≫1s\gg 1 and any x∈𝒜λsx\in\mathcal{A}^{s}_{\lambda} (or x∈𝒜λ∞x\in\mathcal{A}^{\infty}_{\lambda}), there is a simplex σ\sigma in the triangulation of Δ\Delta, verifying ⟨x,m⟩+λ⁡(m)<Lλ​(x)−δ1\langle x,m\rangle+\lambda(m)<L_{\lambda}(x)-\delta_{1} for m∈Δℤ∖σm\in\Delta_{\mathbb{Z}}\setminus\sigma.
