Web为解决这些问题，E.M.Stein和R.Fefferman等人引入一套多参数乘积型的奇异积分算子理论[5-7]，很好地解决了这些问题。这套多参数理论的特点是把单参数理论中的核函数大小条件与光滑性条件同时降低，但是却加强了消失矩条件，依然能保证这类算子的Lp有界性 (1. Webattention when C. Fefferman proved that BMO is the dual of the (real) Hardy space H 1 in 1971. In the past 30 years, this space was studied extensively by many mathematicians. With the help of BMO , many phenomena can be char-acterized clearly. In this review we discuss the connections between BMO
