众所周知,如果Calderón-Zygmund算子T满足T^*(1)=0,则算子T在H^p,n/(n+ε)〈p≤1上有界。这一经典结果的最新推广形式是:如果Calderón-Zygmund算子T满足T^*(b)=0,则算子T是从经典Hardy空间H^p到一类新的Hardy空间Hb^p有界的,其中b是一个拟增长函数.本文建立了算子Tb从新的Hardy空间Hb^p到自身或到经典Hardy空间H^p的有界性,并结合已知的结果,完备了Calderón-Zygmund算子在Hardy空间上的有界性.
It is well known that Calderón-Zygmund operators T are bounded on H^p for n/n+ε 〈 P ≤ 1 provided T^*(1) = 0. accretive function, was recently introduced A new Hardy space Hb^p, where b is a para- and the boundedness of Calderón-Zygmund operators T from the classical Hardy space H^p to the new Hardy space Hb^p was also proven if T^*(b) = 0. In this note, the boundedness from the new Hardy space Hb^p to either Hb^p or H^p is obtained. These results together with the results mentioned above complete the boundedness of Calderón-Zygmund operators on Hardy spaces.
