Effective Bialynicki-Birula-Brosnan motivic decompositions
Charles De Clercq
Let be an isotropic reductive group and be a projective -homogeneous variety. Using results from Bialynicki-Birula, Hesselink and Iversen, Brosnan showed that if is…

Higher Tate traces of Chow motives
Charles De Clercq, Anne Quéguiner-Mathieu
We establish the complete classification of Chow motives of projective homogeneous varieties for -inner semi-simple algebraic groups, with coefficients in $\mathbb{Z}/p\mathbb{Z…
