Complexes of Sheaves and their Hypercohomology,. Oka [.] and H. Cartan himself), and by J. Leray in topology [.]. Since then sheaves have become important in many other branches of mathematics. Whenever one wants to investigate global properties of geometric objects like functions, bundles, and so on, sheaves come into play. There are many excel反馈 发表于 2025-3-23 22:59:38
Line Bundles and Central Extensions,. This group turns out to be isomorphic to a Deligne cohomology group (§2.2). In fact Deligne cohomology provides a tool for constructing line bundles with connections. If the infinitesimal action of some Lie algebra on the underlying manifold preserves the isomorphism class of (., ∇), then a centra杀人 发表于 2025-3-24 03:48:26

First, recall from how the space . of smooth loops .. → . is made into a smooth manifold, modelled on the topological vector space ..(..,ℝ.). This vector space has the structure of an ILH space (inverse limit of Hilbert spaces) in the sense of §1.4.现存 发表于 2025-3-24 09:36:53

Degree 3 Cohomology: Sheaves of Groupoids,ry of descent for sheaves, based on local homeomorphisms. In §2, we introduce sheaves of groupoids (also called stacks) and gerbes. We relate gerbes on . with band a sheaf of abelian groups . with the cohomology group ..(.). A gerbe with band ..* is called a Dixmier-Douady sheaf of groupoids. In §3commune 发表于 2025-3-24 17:05:09

These chemical tags attach to all peptides in a protein digest via free amines at the peptide N-terminus and on the side chain of lysine residues. Labelled samples包庇 发表于 2025-3-24 19:27:29

Thus, the identification of sites of post-translational modification is crucial for fully deciphering the biological roles of any given protein.
