Abstract: In the seminal paper of Ronald Coifman and Guido Weiss (Bull. Amer. Math. Soc. 83 (1977), no. 4, 569-645), a general theory of Hardy spaces over abstract spaces of homogeneous type has been introduced and studied. There, they proved that the Hardy space H1 is in fact the dual space of VMO (vanishing mean oscillation) a subspace of BMO. This allows us to study the weak*-convergence in H1. In this talk, we will present some recent results related to the weak*-convergence in the Hardy-type spaces.
