Dimension Independent Atomic Decomposition for Dyadic Martingale $$ \pmb {{\mathbb {H}}}^{1}$$ H 1
arxiv(2022)
摘要
We introduce atoms for dyadic atomic
$${\mathbb {H}}^1$$
for which the equivalence between the atomic and maximal function definitions is dimension independent. We give sharp, up to
$$\log (d)$$
factor, estimates for the
$${{\mathbb {H}}^1}\rightarrow L^1$$
norm of the special maximal function.
