Local Riesz transforms characterization of local Hardy spaces
For 0 < p ≤ 1, let hp(Rn) denote the local Hardy space. Let θ̂ be a smooth, compactly supported function, which is identically one in a neighborhood of the origin. For k = 1, . . . , n, let (rkf )̂ (ξ) = −i(1 − θ̂(ξ))ξk/|ξ|f̂(ξ) be the local Riesz transform and define (r0f )̂ (ξ) = (1 − θ̂(ξ))f̂(ξ). Let Ψ be a fixed Schwartz function with ∫ Ψ dx = 1, letM > 0 be an integer and suppose (n− 1)/(n+M − 1)...
متن کاملHardy Spaces and Heat Kernel Regularity
In this article, we will be concerned with questions related to the boundedness of the Riesz transform on manifolds. Since the seminal work of Coulhon and Duong [4], who gave sufficient conditions on the heat kernel so that the Riesz transform is bounded on Lp for 1 < p ≤ 2, several authors have investigated both necessary and sufficient conditions for the boundedness of the Riesz transform on ...
متن کاملThe Heat Kernel and the Riesz Transforms on the Quaternionic Heisenberg Groups
As the heat kernel plays an important role in many problems in harmonic analysis, an explicit usable expression is very much desirable. An explicit expression for the heat kernel for the Heisenberg group Hn = C ×R was obtained by Hulanicki [9] and by Gaveau [7]. Gaveau [7] also obtained the heat kernel for free nilpotent Lie groups of step two. Cygan [4] obtained the heat kernel for all nilpote...
متن کاملWeak Type Estimates of the Maximal Quasiradial Bochner-riesz Operator on Certain Hardy Spaces
LetM be a real-valued n×nmatrix whose eigenvalues have positive real parts. Then we consider the dilation group {At}t>0 in R generated by the infinitesimal generator M , where At = exp(M log t) for t > 0. We introduce At-homogeneous distance functions ̺ defined on R; that is, ̺ : R → [0,∞) is a continuous function satisfying ̺(Atξ) = t̺(ξ) for all ξ ∈ R. One can refer to [3] and [11] for its fundam...
متن کاملSub-gaussian Estimates of Heat Kernels on Infinite Graphs
We prove that a two-sided sub-Gaussian estimate of the heat kernel on an infinite weighted graph takes place if and only if the volume growth of the graph is uniformly polynomial and the Green kernel admits a uniform polynomial decay.
