A1-contractibility of Koras-Russell threefolds
Marc Hoyois, Amalendu Krishna, Paul Arne Østvær
Finite suspensions of Koras-Russell threefolds are contractible in A1-homotopy theory.

Motivic homotopy theory of group scheme actions
Jeremiah Heller, Amalendu Krishna, Paul Arne Ostvaer
We define an unstable equivariant motivic homotopy category for an algebraic group over a Noetherian base scheme. We show that equivariant algebraic -theory is representable in…

Motivic homotopy of group scheme actions
Amalendu Krishna, Paul Arne Ostvaer
To smooth schemes equipped with a smooth affine group scheme action, we associate an equivariant motivic homotopy category. Underlying our construction is the choice of an `equivar…
