doi:10.1090/mcom/3528engAdell, JALekuona, ARational approximation to Euler's constant at a geometric rate of convergenceART-2020-118885We give a rational approximation to Euler''s constant at a geometric rate of convergence, which is easy to compute. Moreover, such an approximation is completely monotonic. The approximants are built up in terms of expectations of the harmonic numbers acting on the standard Poisson process.2020http://zaguan.unizar.es/record/13045910.1090/mcom/3528http://zaguan.unizar.es/record/130459oai:zaguan.unizar.es:130459info:eu-repo/grantAgreement/ES/DGA/E64info:eu-repo/grantAgreement/ES/MINECO/MTM2015-67006-PMATHEMATICS OF COMPUTATION 89, 325 (2020), 2553-2561by-ndhttp://creativecommons.org/licenses/by-nd/3.0/es/info:eu-repo/semantics/openAccess
