Locally Free Sheaves
In these talks we will discuss several important examples of locally free sheaves and see the connection between locally free sheaves and finitely generated projective modules. In addition, we will see the connection between the divisor class group and the Picard group (aka ideal class group) of a domain. The bulk of this talk is taken from Sections 5 and 6 of Chapter II of [3]. Proofs of the v...
متن کاملExtending locally truncated chamber systems by sheaves
We generalize the theory of sheaves to chamber systems. We prove that, given a chamber system C and a family R of proper residues of C containing all residues of rank c1, every sheaf defined over R admits a completion which extends C. We also prove that, under suitable hypotheses, a sheaf defined over a truncation of C can be extended to a sheaf for C. In the last section of this paper, we appl...
متن کاملParametrized Spaces Are Locally Constant Homotopy Sheaves
We prove that the homotopy theory of parametrized spaces embeds fully and faithfully in the homotopy theory of simplicial presheaves, and that its essential image consists of the locally homotopically constant objects. This gives a homotopy-theoretic version of the classical identification of covering spaces with locally constant sheaves. We also prove a new version of the classical result that...
متن کاملMorita Cohomology and Homotopy Locally Constant Sheaves
We identify Morita cohomology, which is a categorification of the cohmology of a topological space X, with the category of homotopy locally constant sheaves of perfect complexes on X.
