Abstract: We present some birational invariants relevant for rationality questions and present a computation of these invariants in some cases; namely for some hypersurfaces and variety of lines of hypersurfaces. We will be especially interested in the Griffiths group Griff1, torsion Cycles annihilated by Deligne cycle map and the decomposition of the diagonal.
