In this note, we mainly investigate the majorizations on the products and sums of matrices. Firstly, we present the following result: Let A i , B i and X i ∈ M n ( C ) ( i = 1 , 2 , ··· , m ) with X i ( i = 1 , 2 , ··· , m ) are invertible matrices, and let h be a nonnegative increasing continuous function on [ 0 , + ∞ ) with h ( 0 ) = 0. If f , g are nonnegative continuous functions on [ 0 , + ∞ ) with f ( t ) g ( t ) = t for t ∈ [ 0 , + ∞ ) , then","PeriodicalId":56274,"journal":{"name":"Operators and Matrices","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71224268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
