WebApr 11, 2024 · We establish a connection between continuous K-theory and integral cohomology of rigid spaces. Given a rigid analytic space over a complete discretely valued field, its continuous K-groups vanish in degrees below the negative of the dimension. Likewise, the cohomology groups vanish in degrees above the dimension. The main result …

WebIn mathematics, de Rham cohomology (named after Georges de Rham) is a tool belonging both to algebraic topology and to differential topology, capable of expressing basic topological information about smooth manifolds in a form particularly adapted to computation and the concrete representation of cohomology classes.
WebThis theorem was rst proven by Atiyah in 1962 [VBKF]. Sections 2 to 4 provide some necessary background to the proof of theorem 1. Section 5 contains the proof. There is a brief discussion on the impossibility of a Kunneth formula for real K theory in seciton 6. In section 7 we provide a stronger Kunneth formula, given by Atiya in [KT]. Finially Webis a re nement of deRham cohomology. We prove the deRham cohomol-ogy classes of a cohesive module only depends on the Z 2-graded topological bundle structure by transgressing the characteristic forms de ned by Chern superconnection to forms de ned by the connection component. In section 3, we prove the characteristic classes in Bott-Chern ...

More-over, we consider self-dual generalized (co)homology theories on spaces that need not satisfy the Witt condition.

WebFeb 19, 2024 · Faltings’ annihilator theorem is an important result in local cohomology theory. Recently, Doustimehr and Naghipour generalized the Falitings’ annihilator theorem. They proved that if R is a homomorphic image of a Gorenstein ring, then f a (M)n = λ b a(M)n, where f b a (M)n := inf{i ∈ N dimSupp(bH a(M)) ≥ n for all t ∈ N} and λ b a(M)n := inf{λ bRp …
