Abstract
We prove an adelic descent result for localizing invariants: for each Noetherian scheme of finite Krull dimension and any localizing invariant , e.g., algebraic K-theory of Bass-Thomason, there is an equivalence , where denotes Beilinson's semi-cosimplicial ring of reduced adeles on . We deduce the equivalence from a closely related cubical descent result, which we prove by establishing certain exact sequences of perfect module categories over adele rings.
