Milnor excision for motivic spectra

Abstract: It is a classical result of Weibel that homotopy invariant algebraic K-theory satisfies excision, in the sense that for any ring $A$ and ideal $I\subset A$, the fiber of $KH(A) \to KH(A/I)$ depends only on $I$ as a nonunital ring. In joint work with Elden Elmanto, Ryomei Iwasa, and Shane Kelly, we show that this is true more generally for any cohomology theory represented by a motivic spectrum.
