Wall-crossing Functors
نویسنده
چکیده
Db(Coh(Aθ λ )) ∼ −→ D(Coh(Aλ)) for two different generic θ, θ′. These derived equivalences will play a crucial role in proving that ImCCv ⊂ Lω[ν]. They were introduced in [BPW, Section 6] under the name of twisting functors. Let us recall from Lecture 3 that abelian localization holds for (λ + nθ, θ) for all n sufficiently large, see Proposition 2.2 there. Also recall that Coh(Aλ) ∼ −→ Coh(Aλ+nθ′) via tensoring with Aλ,nθ′ , where ? stands for θ or θ′. So we can set WCθ←θ′ = LLoc θ λ+nθ′ ◦RΓ ′ λ+nθ′ ,

We study Translation functors and Wall-Crossing functors on inn-nite dimensional representations of a complex semisimple Lie algebra using D-modules. This functorial machinery is then used to prove the Endomorphism-theorem and the Structure-theorem; two important results were established earlier by W. Soergel in a totally diierent way.

متن کاملDerived Functors Related to Wall Crossing
The setting is the representation theory of a simply connected, semisimple algebraic group over a field of positive characteristic. There is a natural transformation from the wall-crossing functor to the identity functor. The kernel of this transformation is a left exact functor. This functor and its first derived functor are evaluated on the global sections of a line bundle on the flag variety...
متن کاملWall-crossing Functors and D-modules
We will be concerned here with infinite dimensional representations of a complex semisimple Lie algebra g . In more detail, let Ug be the universal enveloping algebra of g , and let Z(g) be the center of Ug . We consider the category of Ug -modules annihilated by a great enough (unspecified) power of a maximal ideal in Z(g) . It is natural to compare the categories corresponding to two differen...
متن کاملFunctors Induced by Cauchy Extension of C$^ast$-algebras
In this paper, we give three functors $mathfrak{P}$, $[cdot]_K$ and $mathfrak{F}$ on the category of C$^ast$-algebras. The functor $mathfrak{P}$ assigns to each C$^ast$-algebra $mathcal{A}$ a pre-C$^ast$-algebra $mathfrak{P}(mathcal{A})$ with completion $[mathcal{A}]_K$. The functor $[cdot]_K$ assigns to each C$^ast$-algebra $mathcal{A}$ the Cauchy extension $[mathcal{A}]_K$ of $mathcal{A}$ by ...
