Dyadic pigeonholing
WebBy dyadic pigeonholing, there are dyadic numbers κ1= κ1(j),κ2= κ2(j), and a collection of ρj×ρj×Rfat tubes Te[ρj] so that (1) Any two Te 1,Te2∈ Te[ρj] either are parallel, or make an angle & ρj/R. (2) Each Te ∈ Te[ρ j] contains ∼ κ1many ρj−1×ρj−1×Rfat tubes in Te[ρj−1]. (3) For each directional cap θ′with d(θ′) = ρj/R1+δ, there are either ∼ κ2 WebNov 12, 2024 · Dyadic pigeonholing makes a small but important role in an important result [9] of Bourgain on the energy-critical nonlinear Schrödinger equation (NLS), discussed in more detail in Kenig's...

WebIt looks like a dyadic pigeonholing argument to me (the presence of the logarithm is a big clue in this regard). One can decompose $\phi_w$ into about $\log \frac{1}{\delta}$ dyadic shells, depending on the magnitude of $ x-w /\delta$, plus a remainder in which $1+ x-w /\delta \geq \delta^{-100B}$ (say) which has a negligible contribution. inconsistent nytWebMay 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.
