WebJun 6, 2024 · Here you need to apply slightly non-standard Littlewood--Paley inequality. It is well known (however, an exact reference does not come to my mind immediately but I believe any proof of standard L.--P. inequality works equally well in this case) that the Littlewood--Paley inequality holds not only for the intervals $[2^j, 2^{j+1})$ but also for … WebThe Littlewood-Paley projections are “projections” in the sense that they are uniformly bounded and decompose a function in Lp(Rd). Thus to study an Lp-function, it suffices to study its frequency localisation. Proposition 1 (Boundedness of Littlewood-Paley projections). Let 1 ≤p ≤∞, then

WebReferring to the wavelet construction method of Littlewood–Paley and Meyer, the empirical wavelet function is constructed. After Λ n is determined, the empirical wavelet is used as a bandpass filter. The formulas of the empirical wavelet function ψ ∧ n (ω) and the empirical scale function ϕ ∧ n (ω) are as follows : Web逯光辉,周 疆(新疆大学数学与系统科学学院,新疆 乌鲁木齐 830046)1 预备知识设μ是定义在d上的正Radon测度且满足下面的增长条
