Dyadic pigeonholing

WebMay 6, 2024 · There are two parts for this paper. In the first part we extend some results in a recent paper by Du, Guth, Li and Zhang to a more general class of phase functions. The main methods are Bourgain–Demeter’s l^2 decoupling theorem and induction on scales. In the second part we prove some positive results for the maximal extension operator for ... Web7. Several reductions through dyadic pigeonholing We now begin the proof of Proposition 5.1. By Claim 5.2, we have a base case: there is >0 for which (6) holds. Fix R>1, which we can choose later as big as we want. To prove (8) we may assume a= 0, nR 12 <" 0 and x f j2L2(V) with kfk 2 = 1 for j= 1;2. By the Lemma 6.1, it su ces to prove that (9 ...
