It is well known fact that the derivative of this function, if exists, can take only two values: 0 and +∞.It isalso known that the value of the derivative ? (x)atthe point x =[0; a1,a2,...,at,...] is connected with the limit behaviour of the arithmetic mean (a1 +a2 +···+at)/t. Particularly, N. Moshchevitin and A. Dushistova showed that if a1+a2+⋯+at<κ1, {a_1} + {a_2} + cdots + {a_t} < {kappa _1}, where κ1=2log(1+52)/log2=1.3884… {kappa _1} = 2log left( {{{1 + sqrt 5 } over 2}} right)/log 2 = 1.3884 ldots , then ?′(x)=+∞.They also proved that the constant κ1 is non-improvable. We consider a dual problem: how small can be the quantity a1 + a2 + ··· + at − κ1t if we know that ? (x) = 0? We obtain the non-improvable estimates of this quantity.","PeriodicalId":23390,"journal":{"name":"Uniform distribution theory","volume":"126 1","pages":"101 - 126"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88087342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
