On the Chow groups of a biquaternion Severi--Brauer variety

Eoin Mackall

We provide an alternative proof that the Chow group of $1$ -cycles on a Severi--Brauer variety associated to a biquaternion division algebra is torsion-free. There are three proofs…

The Period and Index of a Generic Geometrically Elliptic Normal Curve

Eoin Mackall

We construct genus one curves on base extensions of generic Severi--Brauer varieties of a given index and period which are versal objects for families of geometrically elliptic nor…

$A^{1}$ -homotopy equivalences and a theorem of Whitehead

Eoin Mackall

We prove analogs of Whitehead's theorem (from algebraic topology) for both the Chow groups and for the Grothendieck group of coherent sheaves: a morphism between smooth projective…
