Lemma 9.5 (Nonlinear Errors).

Consider (ℳ,gβ)(\mathcal{M},g_{\beta}) with sufficiently large gluing parameter β≫1\beta\gg 1. Let δ\delta, ν\nu and μ\mu be the constants in Proposition 9.2, then there are constants r0>0r_{0}>0 and C>0C>0 which are independent β\beta, such that for every 𝐯1≡(𝛈1,𝛏¯1+)∈Br​(0)⊂𝔄\bm{v}_{1}\equiv(\bm{\eta}_{1},\bar{\bm{\xi}}_{1}^{+})\in B_{r}(0)\subset\mathfrak{A} and 𝐯2≡(𝛈2,𝛏¯2+)∈Br​(0)⊂𝔄\bm{v}_{2}\equiv(\bm{\eta}_{2},\bar{\bm{\xi}}_{2}^{+})\in B_{r}(0)\subset\mathfrak{A}, where r<r0r<r_{0}, we have
