The ﬁrst contribution comes from Q∗ (∆J ( αj ωj )). It is estimated in Lemma 6. We have: Q∗ ∆J αj ωj w = O(Γi )|w|H01 . Next, we have the contribution of O ω 4 (|v k | + |hk | + |k ∗ |) + |v k |5 + |hk |5 + |k ∗ |5 k=i which, by Lemma 8, is o(Γi )|w|H01 . Next, we have the contribution of hi which we trace back to Lemmas 9– 10 and Lemma 11. It is o(Γi )|w|H01 except for ωi4 |hi ||w| which yielded a contribution equal to 1 √ λi |w|H01 o(Γi ) + |w|H01 0 Max |hi | . Bi /2 −Bj We revisit this estimate using Lemma 12.
Furthermore, the coeﬃcient of the line i of C r are obtained after multiplication of the line i of C with the columns of C r−1 . The estimate on − ej L−1 ei provided above yields then the result. 4 Towards an H01 -estimate on v i and an L∞ -estimate on hi We would like to derive an H01 -estimate on vi and an L∞ -estimate on hi . 12) and we also need to estimate each term in fi w, where w ∈ H01 (Ωi ). We start with: Lemma 8 O |ω |4 (|v k | + |hk | + |k ∗ |) + |v k |5 + |hk |5 + |k ∗ |5 ∂ωi ≤ k=i C Proof.
