Wavelet characterization of Hörmander symbol class $S_{ρ, δ}^{m}$ and applications

Q X Yang

In this paper, we characterize the symbol in Hörmander symbol class $S_{ρ, δ}^{m} (m \in R, ρ, δ \geq 0)$ by its wavelet coefficients. Consequently, we analyse the kernel-distribution…

$L^{p}$ -continuity for Calderón--Zygmund operator

Q X Yang

Given a Calderón--Zygmund (C--Z for short) operator $T$ , which satisfies Hörmander condition, we prove that: if $T$ maps all the characteristic atoms to $W L^{1}$ , then $T$ is conti…
