The Intrinsic Normal Cone for Artin Stacks

نویسندگان

چکیده

We extend the construction of normal cone a closed embedding schemes to any locally morphism finite type higher Artin stacks and show that in Deligne-Mumford case our recovers relative intrinsic Behrend Fantechi. characterize extension as unique one satisfying short list axioms, use it construct deformation cone. As an application methods, we associate equipped with choice global perfect obstruction theory virtual fundamental class Chow group Kresch.

Sheaves on Artin Stacks

We develop a theory of quasi–coherent and constructible sheaves on algebraic stacks correcting a mistake in the recent book of Laumon and Moret-Bailly. We study basic cohomological properties of such sheaves, and prove stack–theoretic versions of Grothendieck’s Fundamental Theorem for proper morphisms, Grothendieck’s Existence Theorem, Zariski’s Connectedness Theorem, as well as finiteness Theo...

Formal Gaga on Artin Stacks

Suppose X is a locally noetherian Deligne–Mumford stack. Definition 1.2 has an obvious variant X̂ét using the underlying smaller étale site Xét and the restriction Oc Xét of Oc X to this site. By [3, 12.7.4], the category of cartesian Oc X -modules on Xlis-ét is equivalent to the category of Oc Xét-modules on Xét: (1.1) ModXlis-ét,cart(Oc X ) ' ModXét(Oc Xét) Definition 1.3. Let X be a locally n...

Tangent Lie algebra of derived Artin stacks

Since the work of Mikhail Kapranov in [Kap], it is known that the shifted tangent complex TX r ́1s of a smooth algebraic variety X is endowed with a weak Lie structure. Moreover any complex of quasi-coherent sheaves on X is endowed with a weak Lie action of this tangent Lie algebra. We will generalize this result to (finite enough) derived Artin stacks, without any smoothness assumption. This in...
