《沦陷区的女人》简介：It is well-known that BMO(Rn) can be characterized via the boundedness of commutators for singular integrals and related operators on the Lebesgue spaces and weighted Lebesgue spaces, and so on. However, the commutators of singular integrals with BMO functions may not be bounded from H1(Rn) to L1(Rn). In this talk, we will introduce that there are certain weighted BMO(Rn), which are nontrivial proper subclass of BMO(Rn), such that commutators generated by singular integrals and related operators with a function belonging to these subclass are bounded from weighted Hp(Rn) to weighted Lp(Rn), or weighted Hp(Rn) to itself, and the converse results related to certain special singular integral operators also hold.
