The associated image-preimage adjunction ( γ L ) − 1 [ − ] ⊣ γ L [ − ] between the frames T ( L ) and TT ( L ) is shown to coincide with the adjunction c T ( L ) ⊣ γ T ( L ) of the second step of the assembly (tower) of L . This helps to explain the role of T ( L ) = S ( L ) op as an “almost discrete lift” (sometimes used as a sort of model of the classical discrete lift DL → L ) as a dispersion going halfway to Booleanness. Consequent use of the concrete sublocales technique simplifies the reasoning. We illustrate it on the celebrated Plewe’s Theorem on ultranormality (and ultrapara-compactness) of S ( L ) which becomes (we hope) substantially more transparent.","PeriodicalId":49652,"journal":{"name":"Quaestiones Mathematicae","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140975796","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}
