| Abstract | Let (X, d, μ) be a metric measure space satisfying both the geometrically doubling and the upper doubling conditions. Let ρ ∈ (1, ∞), 0 < p ⩽ 1 ⩽ q ⩽ ∞, p ≠ q, γ ∈ [1, ∞) and ε ∈ (0, ∞). In this paper, the authors introduce the atomic Hardy space $$\tilde H_{atb,\rho }^{p,q,\gamma } (\mu )$$ and the molecular Hardy space $$\tilde H_{mb,\rho }^{p,q,\gamma ,\varepsilon } (\mu )$$ via the discrete coefficient $$\tilde K_{B,S}^{(\rho ),p}$$ , and prove that the Calderón-Zygmund operator is bounded from $$\tilde H_{mb,\rho }^{p,q,\gamma ,\delta } (\mu )$$ (or $$\tilde H_{atb,\rho }^{p,q,\gamma } (\mu )$$ ) into L $^{ p }$(μ), and from $$\tilde H_{atb,\rho (\rho + 1)}^{p,q,\gamma + 1} (\mu )$$ into $$\tilde H_{mb,\rho }^{p,q,\gamma ,\tfrac{1} {2}(\delta - \tfrac{v} {p} + v)} (\mu )$$ . The boundedness of the generalized fractional integral T $_{ β }$ (β ∈ (0, 1)) from $$\tilde H_{mb,\rho }^{p_1 ,q,\gamma ,\theta } (\mu )$$ (or $$\tilde H_{atb,\rho }^{p_1 ,q,\gamma } (\mu )$$ ) into $$L^{p_2 } (\mu )$$ with 1/p $_{2}$ = 1/p $_{1}$−β is also established. The authors also introduce the ρ-weakly doubling condition, with ρ ∈ (1, ∞), of the measure μ and construct a non-doubling measure μ satisfying this condition. If μ is ρ-weakly doubling, the authors further introduce the Campanato space $$\mathcal{E}_{\rho ,\eta ,\gamma }^{\alpha ,q} (\mu )$$ and show that $$\mathcal{E}_{\rho ,\eta ,\gamma }^{\alpha ,q} (\mu )$$ is independent of the choices of ρ, η, γ and q; the authors then introduce the atomic Hardy space $$\hat H_{atb,\rho }^{p,q,\gamma } (\mu )$$ and the molecular Hardy space $$\hat H_{mb,\rho }^{p,q,\gamma ,\varepsilon } (\mu )$$ , which coincide with each other; the authors finally prove that $$\hat H_{atb,\rho }^{p,q,\gamma } (\mu )$$ is the predual of $$\mathcal{E}_{\rho ,\rho ,1}^{1/p - 1,1} (\mu )$$ . Moreover, if μ is doubling, the authors show that $$\mathcal{E}_{\rho ,\eta ,\gamma }^{\alpha ,q} (\mu )$$ and the Lipschitz space Lip$_{ α, q }$(μ) (q ∈ [1, ∞)), or $$\hat H_{atb,\rho }^{p,q,\gamma } (\mu )$$ and the atomic Hardy space H at p, q (μ) (q ∈ (1, ∞]) of Coifman and Weiss coincide. Finally, if (X, d, μ) is an RD-spac (reverse doubling space) with μ(X) = ∞, the authors prove that $$\tilde H_{atb,\rho }^{p,q,\gamma } (\mu )$$ , $$\tilde H_{mb,\rho }^{p,q,\gamma ,\varepsilon } (\mu )$$ and H at p, q (μ) coincide for any q ∈ (1, 2]. In particular, when (X, d, μ):= (ℝ$^{ D }$, |·|, dx) with dx being the D-dimensional Lebesgue measure, the authors show that spaces $$\tilde H_{atb,\rho }^{p,q,\gamma } (\mu )$$ , $$\tilde H_{mb,\rho }^{p,q,\gamma ,\varepsilon } (\mu )$$ , $$\hat H_{atb,\rho }^{p,q,\gamma } (\mu )$$ and $$\hat H_{mb,\rho }^{p,q,\gamma ,\varepsilon } (\mu )$$ all coincide with H $^{ p }$(ℝ$^{ D }$) for any q ∈ (1, ∞). |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
