Abstract:
We present a version of projective bundle theorem in MW-motives (resp.
Chow-Witt rings), which says that
(ℙ(E)) is
determined by
(X)
and
(X × ℙ²)
for smooth quasi-projective schemes X and vector bundles E over X with
odd rank. If the rank of E is even, the theorem is still true under a new
kind of orientability, which we call it by projective orientability.
