摘要
在文中，刻划了BMOA空间的循环元，得到了f是BMOA空间循环元的充分必要条件是f为外函数．
In this paper we try to identify the funciton whose polynomial multiples arcweak' dense in thc BMOA space. Wc obtain that if l f(z) l > 1 g(z) I at all points and if gis cyclic, then f is cyclic, Theorem 2 gives a sufficient and nccessary condition for a functionto be cyclic is that f is an outer function.
