Schubert cycles and subvarieties of generalized Severi-Brauer varieties
Caroline Junkins, Daniel Krashen, Nicole Lemire
We study twisted forms of Schubert cells in generalized Severi-Brauer varieties, and show that the codimension Chow groups of these varieties are torsion free in certain cases,…

Twisted gamma filtration and algebras with orthogonal involution
Caroline Junkins
For the Grothendieck group of a split simple linear algebraic group, the twisted gamma-filtration provides a useful tool for constructing torsion elements in gamma-rings of twisted…

The J-invariant and Tits algebras for groups of inner type E6
Caroline Junkins
A connection between the indices of the Tits algebras of a split linear algebraic group G and the degree one parameters of its motivic J-invariant was introduced by Queguiner-Mathi…
