Local Hardy and bmo Spaces on Filtered Lie Groups

Abstract

We develop a theory of local Hardy and $bmo$ spaces on a connected Lie group with polynomial growth whose Lie algebra is endowed with a filtration. Under suitable assumptions, we prove that the local Hardy spaces enjoy an appropriate atomic decomposition, are compatible with Calderón--Zygmund operators, and can be identified with certain Triebel--Lizorkin spaces, as it happens in the classical settings.
