Endpoint estimates of linear commutators on Hardy spaces over spaces of homogeneous type

摘要

> Let ( X , d , μ ) be a metric measure space of homogeneous type in the sense of Coifman and Weiss. In this article, the authors prove that bilinear operators, which are finite combinations of compositions of commutators and Calderón‐Zygmund operators, are bounded from H 1 ( X ) × BMO ( X ) to L 1
