In this article, we define the determinant of such that it agrees with the classical … Witryna13 kwi 2024 · on the complement of D.. We view \(\mathcal {B}\) as an extension of \(\mathcal {A}\) along D, with specifically prescribed modified behavior.In other words, we view M as stratified \(D \subset M\) and we ask for factorization algebras that agree with \(\mathcal {A}\) on the big stratum \(M - D\).When \(\mathcal {A}\) is the algebra of …

WitrynaProof. Since sheafification is exact it is clear that is an exact sequence of abelian sheaves. Thus is an exact sequence of abelian presheaves. To see that is surjective, pick a set theoretical section . This induces a section of sheaves of sets left inverse to the surjection . Lemma 18.42.2. Let be a site. Let be a ring and let and be -modules.

Given a representation ˆ: ˇ 1(X) !Gl(V), the sheaf of cross sections of X~ V=ˇ 1(X) !Xis locally constant, where ˇ 1(X) act on the universal cover X~ in the usual way, and ...
