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 affine group scheme action. We also show that the equivar

Rigidity in equivariant algebraic $K$-theory

Autor: Charanya Ravi, Niko Naumann

Publikováno v: Ann. K-Theory 5, no. 1 (2020), 141-158

If [math] is a henselian pair with an action of a finite group [math] and [math] is an integer coprime to [math] such that [math] , then the reduction map of mod- [math] equivariant [math] -theory spectra ¶ K G ( R ) ∕ n → ≃ K G ( R ∕ I ) �

Rigidity for equivariant pseudo pretheories

Autor: Jeremiah Heller, Paul Arne Østvær, Charanya Ravi

We prove versions of the Suslin and Gabber rigidity theorems in the setting of equivariant pseudo pretheories of smooth schemes over a field with an action of a finite group. Examples include equivariant algebraic $K$-theory, presheaves with equivari

Equivariant vector bundles, their derived category and $K$-theory on affine schemes

Autor: Charanya Ravi, Amalendu Krishna

Publikováno v: Ann. K-Theory 2, no. 2 (2017), 235-275

Let $G$ be an affine group scheme over a noetherian commutative ring $R$. We show that every $G$-equivariant vector bundle on an affine toric scheme over $R$ with $G$-action is extended from $\Spec(R)$ for several cases of $R$ and $G$. We show that g
