(mathcal {P}F) is the complete boolean algebra of polars of the frame F. A function (mathfrak {X}) that assigns to each (F in mathfrak {KNJ}) a subalgebra (mathfrak {X}(F)) of (mathcal {P}F) that contains the complemented elements of F is a polar function. A polar function (mathfrak {X}) is invariant (resp., functorial) if whenever (phi : F longrightarrow H in mathfrak {KNJ}) is (mathcal {P})-essential (resp., skeletal) and (p in mathfrak {X}(F)), then (phi (p)^{perp perp } in mathfrak {X}(H)). (phi : F longrightarrow H in mathfrak {KNJ}) is (mathfrak {X})-splitting if (phi ) is (mathcal {P})-essential and whenever (p in mathfrak {X}(F)), then (phi (p)^{perp perp }) is complemented in H. (F in mathfrak {KNJ}) is (mathfrak {X})-projectable means that every (p in mathfrak {X}(F)) is complemented. For a polar function (mathfrak {X}) and (F in mathfrak {KNJ}), we construct the least (mathfrak {X})-splitting frame of F. Moreover, we prove that if (mathfrak {X}) is a functorial polar function, then the class of (mathfrak {X})-projectable frames is a (mathcal {P})-essential monoreflective subcategory of (mathfrak {KNJS}), the category of (mathfrak {KNJ})-objects and skeletal maps (the case (mathfrak {X}= mathcal {P}) is the result from Martínez and Zenk, which states that the class of strongly projectable (mathfrak {KNJ})-objects is a reflective subcategory of (mathfrak {KNJS})).</div>","PeriodicalId":7952,"journal":{"name":"Applied Categorical Structures","volume":"32 5","pages":""},"PeriodicalIF":0.6,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208869","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}

Similarly, (mathscr {P})-affine schemes can be defined as objects of the opposite of the category of algebras over an operad (mathscr {P}). An example is the opposite of the category of associative algebras. The category of operadic schemes of an operad carries a canonical tangent structure. This paper aims to initiate the study of the geometry of operadic affine schemes via this tangent category. For example, we expect the tangent structure over the opposite of the category of associative algebras to describe algebraic non-commutative geometry. In order to initiate such a program, the first step is to classify differential bundles, which are the analogs of vector bundles for differential geometry. In this paper, we prove that the tangent category of affine schemes of the enveloping operad (mathscr {P}^{(A)}) over a (mathscr {P})-affine scheme A is precisely the slice tangent category over A of (mathscr {P})-affine schemes. We are going to employ this result to show that differential bundles over a (mathscr {P})-affine scheme A are precisely A-modules in the operadic sense.</div>","PeriodicalId":7952,"journal":{"name":"Applied Categorical Structures","volume":"32 5","pages":""},"PeriodicalIF":0.6,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208870","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}
