  • Ravi, Charanya (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    We prove a Grothendieck–Lefschetz theorem for equivariant Picard groups of non-singular varieties with finite group actions.
  • Krishna, Amalendu; Ravi, Charanya (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We prove some fundamental results like localization, excision, Nisnevich descent, and the regular blow-up formula for the algebraic K-theory of certain stack quotients of schemes with affine group scheme actions. We show ...
  • Krishna, Amalendu; Ravi, Charanya (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Let GG be an affine group scheme over a noetherian commutative ring RR. We show that every GG-equivariant vector bundle on an affine toric scheme over RR with GG-action is equivariantly extended from Spec ( R ) Spec(R) for ...
  • Heller, Jeremiah; Ravi, Charanya; Østvær, Paul Arne (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    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, ...
