Spaces of Type BLO on Non-homogeneous Metric Measure Spaces (1009.0839v2)

Abstract: Let $({\mathcal X}, d, \mu)$ be a metric measure space and satisfy the so-called upper doubling condition and the geometrically doubling condition. In this paper, the authors introduce the space ${\mathop\mathrm{RBLO}}(\mu)$ and prove that it is a subset of the known space ${\mathop\mathrm{RBMO}}(\mu)$ in this context. Moreover, the authors establish several useful characterizations for the space ${\mathop\mathrm{RBLO}}(\mu)$. As an application, the authors obtain the boundedness of the maximal Calder\'on-Zygmund operators from $L^\infty(\mu)$ to ${\mathop\mathrm{RBLO}}(\mu)$.
