A framework for non-homogeneous analysis on metric spaces, and the RBMO space of Tolsa. (English) Zbl 1246.30087
Summary: A new class of metric measure spaces is introduced and studied. This class generalises the well-established doubling metric measure spaces as well as the spaces \((\mathbb{R}^n,\mu)\) with \(\mu(B(x,r))\leq Cr^d\), in which non-doubling harmonic analysis has recently been developed. It seems to be a promising framework for an abstract extension of this theory. Tolsa’s space of regularised BMO functions is defined in this new setting, and the John-Nirenberg inequality is proven.
