In this chapter we introduce and study the space of functions of (p, q)-bounded central mean oscillations BCMOp,q on unbounded Ahlfors regular sets, which extends the scale of bounded central p-mean oscillations functions BCMOp discussed in Chapter 5. We begin by establishing some basic functional analytic properties of BCMOp,q, with the ultimate goal of proving that the dual of first-generation Herz-type Hardy spaces HAp,q coincides with BCMOp′ ,q modulo constants.

摘要

In this chapter we introduce and study the space of functions of (p, q)-bounded central mean oscillations BCMOp,q on unbounded Ahlfors regular sets, which extends the scale of bounded central p-mean oscillations functions BCMOp discussed in Chapter 5. We begin by establishing some basic functional analytic properties of BCMOp,q, with the ultimate goal of proving that the dual of first-generation Herz-type Hardy spaces HAp,q coincides with BCMOp′ ,q modulo constants.
