The stacky concentration theorem
Dhyan Aranha, Adeel A. Khan, Alexei Latyntsev +2
We give a sufficient criterion for the Chow or algebraic bordism groups of an algebraic stack, localized at a set of Chern classes of line bundles, to be concentrated in some close…
The chow weight structure for geometric motives of quotient stacks
Dhyan Aranha, Chirantan Chowdhury
We construct the Chow weight structure on the derived category of geometric motives with arbitrary coefficients for X a finite type scheme over a field characteristic 0 and G an af…
Virtual localization revisited
Dhyan Aranha, Adeel A. Khan, Alexei Latyntsev +2
Let be a split torus acting on an algebraic scheme with fixed locus . Edidin and Graham showed that on localized -equivariant Chow groups, (a) push-forward alon…
The Intrinsic Normal Cone For Artin Stacks
Dhyan Aranha, Piotr Pstrągowski
We extend the construction of the normal cone of a closed embedding of schemes to any locally of finite type morphism of higher Artin stacks and show that in the Deligne-Mumford ca…
