We call this new method a $lambda^2-$statistical convergence and denote by $S_{lambda^2}$ the set of sequences which are $lambda^2-$statistically convergent. We find its relation to statistical convergence and strong $(N, lambda^2)-$summability. We will define a new sequence space and will show that it is Banach space. Also we will prove the second Korovkin type approximation theorem for $lambda^2$-statistically summability and the rate of $lambda^2$-statistically summability of a sequence of positive linear operators defined from $C_{2pi}(mathbb{R})$ into $C_{2pi}(mathbb{R}).$","PeriodicalId":45664,"journal":{"name":"Thai Journal of Mathematics","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2019-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42739138","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}
