We show how this leads to precise and computable numerical bounds for this constant.10 p.application/pdfeng(c) Mathematical Sciences Publishers (MSP), 2004Funcions de variables complexesInterpolació (Matemàtica)Anàlisi funcionalÀlgebres de BanachFunctions of complex variablesInterpolationFunctional analysisBanach algebrasinfo:eu-repo/semantics/article5065802020-06-08info:eu-repo/semantics/openAccess
