DESCRIPTION:Let k be a field and E a motivic spectrum over k w
hich is n-torsion for some n invertible in k. We s
how that the cohomology theory on k-schemes define
d by E satisfies Milnor excision. More generally\,
we give necessary and sufficient conditions for a
cdh sheaf to satisfy Milnor excision\, following
ideas of Bhatt and Mathew. Along the way\, we show
that the cdh &infin\;-topos of a quasi-compact qu
asi-separated scheme of finite valuative dimension
is hypercomplete\, extending a theorem of Voevods
ky to nonnoetherian schemes.
