摘要：We prove some Calderón-Zygmund type decompositions for functions in the tent spaces introduced by Coifman, Meyer and Stein. These decompositions will be useful in the operator theory on tent spaces. As an application of these decompositions to the study of quadratic functionals on tent spaces, we give a unified proof for tent space generalizations of C. Fefferman's endpoint weak-type estimates for grand square functions and of C. Fefferman and Stein's endpoint weak-type estimates for box maximal functions.
