Generalized cohomology theories for algebraic stacks

  title={Generalized cohomology theories for algebraic stacks},
  author={A. Khan and Charanya Ravi},
We extend the stable motivic homotopy category of Voevodsky to the class of scalloped algebraic stacks, and show that it admits the formalism of Grothendieck’s six operations. Objects in this category represent generalized cohomology theories for stacks like algebraic K-theory, as well as new examples like genuine motivic cohomology and algebraic cobordism. These cohomology theories admit Gysin maps and satisfy homotopy invariance, localization, and Mayer–Vietoris. We also prove a fixed point… Expand


The six operations in equivariant motivic homotopy theory
Abstract We introduce and study the homotopy theory of motivic spaces and spectra parametrized by quotient stacks [ X / G ] , where G is a linearly reductive linear algebraic group. We extend to thisExpand
Bredon-style homology, cohomology and Riemann-Roch for algebraic stacks
One of the main obstacles for proving Riemann–Roch for algebraic stacks is the lack of cohomology and homology theories that are closer to the K-theory and G-theory of algebraic stacks than theExpand
Equivariant intersection theory
In this paper we develop an equivariant intersection theory for actions of algebraic groups on algebraic schemes. The theory is based on our construction of equivariant Chow groups. They areExpand
Fundamental classes in motivic homotopy theory
We develop the theory of fundamental classes in the setting of motivic homotopy theory. Using this we construct, for any motivic spectrum, an associated bivariant theory in the sense ofExpand
Algebraic K-theory of quotient stacks
We prove some fundamental results like localization, excision, Nisnevich descent and the Mayer-Vietoris property for equivariant regular blow-up for the equivariant K-theory of schemes with an affineExpand
We develop a theory of unbounded derived categories of quasicoherent sheaves on algebraic stacks. In particular, we show that these categories are compactly generated by perfect complexes for stacksExpand
The intrinsic stable normal cone
We construct an analog of the intrinsic normal cone of Behrend-Fantechi in the equivariant motivic stable homotopy category over a base-scheme B and construct a fundament class in E-cohomology forExpand
Vanishing theorems for the negative K-theory of stacks
We prove that the homotopy algebraic K-theory of tame quasi-DM stacks satisfies cdh-descent. We apply this descent result to prove that if X is a Noetherian tame quasi-DM stack and i < -dim(X), thenExpand
Cdh descent in equivariant homotopy K-theory
We construct geometric models for classifying spaces of linear algebraic groups in G-equivariant motivic homotopy theory, where G is a tame group scheme. As a consequence, we show that theExpand
On the algebraic K-theory of higher categories
We prove that Waldhausen K-theory, when extended to a very general class of quasicategories, can be described as a Goodwillie differential. In particular, K-theory spaces admit canonical (connective)Expand
