Abstract
Given a Calderón-Zygmund (C-Z for short) operatorT, which satisfies Hörmander condition, we prove that: ifT maps all the characteristic atoms toWL 1, thenT is continuous fromL p toL p(1 <p < ∞). So the study of strong continuity on arbitrary function inL p has been changed into the study of weak continuity on characteristic functions.
