Abstract

Let $\mu$ be a Radon measure on $\mathbb{R}^d$ which may be non doubling. The only condition that $\mu$ must satisfy is the size condition $\mu(B(x,r))\le Cr^n$ for some fixed $n\in(0,d]$ . Recently, Tolsa introduced the spaces $RBMO(\mu)$ and $H^{1,\infty}_{atb}(\mu)$ , which, in some ways, play the role of the classical spaces

and

in case $\mu$ is a doubling measure. In this paper, the author considers the local versions of the spaces $RBMO(\mu)$ and $H^{1,\infty}_{atb}(\mu)$ in the sense of Goldberg and establishes the connections between the spaces $RBMO(\mu)$ and $H^{1,\infty}_{atb}(\mu)$ with their local versions. An interpolation result of linear operators is also given.
