{"title":"Real-Variable Characterizations of Hardy–Lorentz Spaces on Spaces of Homogeneous Type with Applications to Real Interpolation and Boundedness of Calderón–Zygmund Operators","authors":"Xilin Zhou, Ziyi He, Dachun Yang","doi":"10.1515/agms-2020-0109","DOIUrl":"https://doi.org/10.1515/agms-2020-0109","url":null,"abstract":"Abstract Let (𝒳, d, μ) be a space of homogeneous type, in the sense of Coifman and Weiss, with the upper dimension ω. Assume that η ∈(0, 1) is the smoothness index of the wavelets on 𝒳 constructed by Auscher and Hytönen. In this article, via grand maximal functions, the authors introduce the Hardy–Lorentz spaces H*p,q(𝒳) H_*^{p,q}left( mathcal{X} right) with the optimal range p∈(ωω+η,∞) p in left( {{omega over {omega + eta }},infty } right) and q ∈ (0, ∞]. When and p∈(ωω+η,1] p in ({omega over {omega + eta }},1] q ∈ (0, ∞], the authors establish its real-variable characterizations, respectively, in terms of radial maximal functions, non-tangential maximal functions, atoms, molecules, and various Littlewood–Paley functions. The authors also obtain its finite atomic characterization. As applications, the authors establish a real interpolation theorem on Hardy–Lorentz spaces, and also obtain the boundedness of Calderón–Zygmund operators on them including the critical cases. The novelty of this article lies in getting rid of the reverse doubling assumption of μ by fully using the geometrical properties of 𝒳 expressed via its dyadic reference points and dyadic cubes and, moreover, the results in the case q ∈ (0, 1) of this article are also new even when 𝒳 satisfies the reverse doubling condition.","PeriodicalId":48637,"journal":{"name":"Analysis and Geometry in Metric Spaces","volume":"8 1","pages":"182 - 260"},"PeriodicalIF":1.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/agms-2020-0109","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49179473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim of the current study is to assess the role and progress of research and training, in the field of Risk Management. We carried out a scientometric analysis to quantify and describe scientific outputs on Risk Management at the global and national level, over the last forty years; in addiction, we conducted a national-level cross-sectional survey to systematically retrieve and assess research and training activities within Italian postgraduate medical programmes in Hygiene and Preventive Medicine. We report increasing scientific production on Risk Management-related topics from 1980 to 2017 at the global level (12% annual increase rate). Clinical Trials and Systematic reviews/meta-analysis make up for respectively 5% and 6% of global scientific output. Italy ranks 4th for scientific production, after USA, UK and Germany. 88% of Italian postgraduate medical programmes in Hygiene and Preventive medicine research on Risk Management, 42% through international collaborations. The main research themes are Healthcare-Associated Infections (HAIs) (97%), analysis of organizational models for safety in healthcare (62%), while training is focused on internships (87%) and academic lectures (73%). While research provides the evidence required to plan, implement and monitor effective interventions in healthcare risk management, training allows its dissemination in a synergic action to promote the value of patient safety and quality of care.</p>","PeriodicalId":48637,"journal":{"name":"Analysis and Geometry in Metric Spaces","volume":"10 1","pages":"76-86"},"PeriodicalIF":0.0,"publicationDate":"2019-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7233657/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68833136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
