This discretization procedure improves an earlier discrete random approximation method due to Diamond et al. (Math Ann 334:1–36, 2006), and refined by Zhang (Math Ann 337:671–704, 2007). We obtain several applications. Our new method is applied to a question posed by Balazard concerning Dirichlet series with a unique zero in their half plane of convergence, to construct examples of very well-behaved generalized number systems that solve a recent open question raised by Hilberdink and Neamah (Int J Number Theory 16(05):1005–1011, 2020), and to improve the main result from (Adv Math 370:Article 107240, 2020), where a Beurling prime system with regular primes but extremely irregular integers was constructed.</p>","PeriodicalId":18278,"journal":{"name":"Mathematische Zeitschrift","volume":"73 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2024-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141509140","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}
