齐次群上的平均振荡空间(Ⅱ)

MEAN OSCILLATION SPACE ON HOMOGENEOUS GROUPS(Ⅱ)

定义了齐次群上一类平均振荡空间，证明了它是一类Ｈａｒｄｙ型空间的对偶空间，由此得到该平均振荡空间的另一等价定义，从而拓广了文献［２］中的结果．

In this paper we define the mean oscillation spaces on the homogeneous group. These spaces are characterized by the conjugate spaces of some Hardy spaces. Hence we extend some results in the paper.
