The Ba space was introduced and studied at first in [1]. It has been effectively applied to the prior estimates for linear partial differential equations, to the calculus of variations with strong nonlinearity, to the error estimations for finite difference methods and to harmonic analysis (cf.[1--8] ). The goal of this report is to study the Littlewood-Paley theory in the Ba spaces. 展开更多

Let (x, d,u) be a metric measure the upper doubling conditions. Under the weak space satisfying both the geometrically doubling and reverse doubling condition, the authors prove that the generalized homogeneous Littlewood-Paley g-function gr (r ∈ [2, ∞)) is bounded from Hardy space H1(u) into L1(u). Moreover, the authors show that, if f ∈ RBMO(u), then [gr(f)]r is either infinite everywhere or finite almost everywhere, and in the latter case, [gr(f)]r belongs to RBLO(u) with the norm no more than ||f|| RBMO(u) multiplied by a positive constant which is independent of f. As a corollary, the authors obtain the boundedness of gr from RBMO(u) into RBLO(u). The vector valued Calderon-Zygmund theory over (X, d, u) is also established with details in this paper. 展开更多

Via the boundedness of intrinsic g-functions from the Hardy spaces with variable exponent,Hp(·)(Rn),into Lebesgue spaces with variable exponent,Lp(·) (Rn),and establishing some estimates on a discrete Littlewood-Paley g-function and a Peetre-type maximal function,we obtain several equivalent characterizations of Hp(·)(Rn) in terms of wavelets,which extend the wavelet characterizations of the classical Hardy spaces.The main ingredients are that,we overcome the difficulties of the quasi-norms of Hp(·)(Rn) by elaborately using an observation and the Fefferman-Stein vector-valued maximal inequality on Lp(·)(Rn),and also overcome the difficulty of the failure of q =2 in the atomic decomposition of Hp(·) (Rn) by a known idea. 展开更多
